Need Help Configuring Postfix Restrictions

Hi i have installed postfix 2.11.3 on debian jessie.Everthing works fine. I would like to restrict local users to send mails to a particular group email id and allow only few users with smtpd_restriction_classes , smtpd_recipient_restrictions following this link <a href="http://www.postfix.net/RESTRICTION_CLASS_README.html" title="http://www.postfix.net/RESTRICTION_CLASS_README.html">http://www.postfix.net/RESTRICTION_CLASS_README.html</a> which is not working. All the users are still able to send mails to the group id. I have the same restriction working fine with postfix 2.9 installed on wheezy.

Virtual host config and non-virtual host directories

I am reading:

<a href="https://httpd.apache.org/docs/2.4/vhosts/examples.html" title="https://httpd.apache.org/docs/2.4/vhosts/examples.html">https://httpd.apache.org/docs/2.4/vhosts/examples.html</a>

And the statement:

"The asterisks match all addresses, so the main server serves no

www.example.com| is first in the configuration file, it has the highest
priority and can be seen as the default or primary server.

logrotate, httpd and piping messages to java program

Hi

I asked following question few days ago:

Reg : Limiting http connections at Apache 2.4.25

Hi Everyone,

I just joined to this group.

I have installed Apache 2.4.25 HTTP server as a reverse proxy server and my

required to achieve this restriction.

My OS is RHEL 7.2, your help and support on this matter is highly
appreciated.

Hiding Apache version info on the Aix server for Apache.

Hi All,

Can anyone please let me know how to hide the apache version and the OS name running on Aix server.

The servertokens or the server signature fields are set to PROD and signature off, then I tried restarting the httpd but apache was not starting until these two parameters are removed from the config file.

Merging multiple aliases files together

I don't know the best way to achieve this.

I have some "user" packages which install various users on a linux
system. I want the setup to be entirely automated, and as part of this
I want to set up some mail aliases for each user, and add their alias
to the root alias. Essentially, the following represents one user:

root: bob
bob: <a href="mailto: ... at example dot com"> ... at example dot com</a>

I have 0 or more of these user packages, and I want to, some how,
merge all these aliases together.

content negotiation default language/file?

Hi,
On my current site with 2.2.31 (<a href="http://www.vishay.com" title="www.vishay.com">www.vishay.com</a>)
I have 3 languages,
English index.html
ja index.ja.html
zh index.zh.html

I am trying to set this up similarly on my new server, 2.4.16.
I can get ja and zh to work, but I can't get it to know that index.html is
english.
Is this still possible or I must name everything index.en.html?
Is there an option I am missing?
Thanks,

TLS support for Postfix server on port TCP/25

Dear, I want mail clients to send messages to Internet through an own mail
relay Posfix as smtpd server (no as client), let's say:

Mail client ---STARTTLS ---- Postfix listening on Port TCP/25 --- Internet
SMTP servers

Also, I don't need authentication to send mails from the Postfix mail relay.

In /etc/postfix/main.cf I setup:

# TLS parameters for smtpd
smtpd_tls_cert_file=/etc/postfix/SSL/MailRelay-server-public.crt

smtpd_tls_key_file=/etc/postfix/SSL/MailRelay-server-private.pem

smtpd_use_tls=yes

enforcing SSL renegotiation for AES-GCM based cipher suites

Dear team
In mod_ssl is there any option to enforce SSL renegotiation after
certain amount of data has been transfered on SSL connection .
If we are using cipher suite which has AES-GCM as encryption algorithm
, then its required that when the counter overlaps or overflows then
SSL renegotiation should happen .
In AES-GCM the final counter is
[4 bytes salt which is negotiated between client and serevr ]
+
[8 bytes of random bytes which are generated for the first time using
RAND_bytes (nonce_explicit).
It is incremented for each TLS packet]

nonconsistent proxy 503 or 502 errors with apache 2.4

Hello,

I'm running a FreeBSD 10.3 server which has an Apache 2.4.25 system
running on it. It's reverse proxying to two web servers example.com
and example2.com hosted in two separate FreeBSD jails.

I'm getting nonconsistent 502 and 503 errors when atempting to access
the systems from the outside.

For example one time I hit example.com and it works. I then go to
example2.com and get either a 502 or 503 message. I try from another
browser this time going to example2.com and it works, but then going
to example.com gives me those same 502 or 503 error messages.

Testing reject_unknown_client_hostname

Hello, in Postfix v3.1 I'm having a hard time getting
reject_unknown_client_hostname to bounce test messages.

I set an external host's Postfix myhostname to be purposefully

system. If I have reject_unknown_helo_hostname enabled, it will reject
such messages.

Question about Postfix/Nginx integration / XCLIENT support

Hi,

I’m playing with using Nginx as an IMAP and SMTP proxy for our mail servers,
as it will help us migrate and horizontally scale.

unused parameter: virtual_mailbox_limit_maps

I found one article:

<a href="https://www.howtoforge.com/community/threads/postfix-warning-undefined-parameter-virtual_mailbox_limit_maps.71474/" title="https://www.howtoforge.com/community/threads/postfix-warning-undefined-parameter-virtual_mailbox_limit_maps.71474/">https://www.howtoforge.com/community/threads/postfix-warning-undefined-p...</a>

that says it is not required anymore. To remove it. I am *assuming*
that I then also remove:

/etc/postfix/mysql-virtual_mailbox_limit_maps.cf

I looked around and did not see anywhere it is being used.

Seems this is a hang over from long ago. Old server does not have this
option, but still has the file.

?

thanks

Obsolete httpd-std.conf in binbuild,sh?

Hi all,

I'm trying to build Apache httpd server 2.4.25 on Ubuntu 4.8.0.
The idea is to embed httpd server into own application and to be able
to install on target machine in any location in file system.
I found the tool $(root src)/build/binbuild.sh which should do exactly
what I want.
After I run binbuild.sh I get an archive
httpd-2.4.25-x86_64-unknown-linux-gnu.tar.gz.
Then I unpack it and run install-bindist.sh <target dir> which deploys httpd.

The only problem I see is the issue with httpd.conf file.

Mod_dav configuration question

Hi

Since a few months we're using WebDAV (apache mod_dav) to serve files
for one of our apps. Everything works alright but when combined with an
older WebDAV client (needed for Office 2010 and older) we're running
into some issues.

The company that made the client has looked into the problem and gives
this as a possible cause for our issues:

Bypass restrictions for postmaster/abuse

Hello all,

Is there a best practices for exempting the postmaster/abuse address
from certain smtpd_mumble_restrictions?

For example, we see some small businesses who have trouble getting past
reject_unknown_helo_hostname and reject_unknown_client_hostname and if
we reach out to them, we need to allow their reply to our postmaster
address to get delivered, obviously bypassing the checks that originally
caused the rejections.

I think each organization will have restrictions that they deem
important enough to place even before exemptions for postmaster, but I'd
like to learn what other

Setting amavis content_filter in main.cf

I am reading the amavis-new readme for postfix.

It almost reads like main.cf should have:

content_filter=amavisfeed:[127.0.0.1]:10024

rather than how I see it all over in master.cf. Its presence as an
option in master.cf is very inconsistent.

Are there services in master.cf that should not have a content_filter to
amavisfeed?

thank you

Supporting legacy clients

Hi!
After upgrading to postfix 3.1 (from 2.9), one of our clients said, it

Using postconf to manage master.cf

I am back to building a new mailserver. I am using Centos7 which has
postfix 2.10.1

to manage master.cf. From

<a href="http://www.postfix.org/postconf.1.html" title="http://www.postfix.org/postconf.1.html">http://www.postfix.org/postconf.1.html</a>

It seems that there are now options here for master.cf, but I cannot
find any guidance on using this.

I am using this directive successfully.

if I also want to send ssl_error_log to this program as well, is there
any provision to do so ?

This is what I was doing when using manual script to launch the log consumer.

Question on embedded variables in postconf command

Is there a way to get the following:

postconf -e 'smtpd_tls_key_file = /etc/pki/tls/private/$myhostname.key'

To work and substitute the value for $myhostname?

I am building a new server and writing up my scripts and I am trying to
adhere to the lessons I learned here some 2+ years ago. And trying to
be better than I was then...

Thank you.

Supported versions

I used to have a bookmark for a page that showed the currently supported versions of Postfix and (I think) when support ended for previous versions). I seem mohave lost the bookmark and I can’t fin the page on postfix.org which makes me think it isn’t there.

I can get the information by going to <http://www.postfix.org/announcements.html> and looking in specific announcements to see what (if any versions) were obsoleted.

Just as an example, I was trying to find when 2.6 support ended, and after going through he major releases I found it in the 2.10 release announcements.

mod_rewrite behavior when port is specified

Hello..

I'm seeing an issue where mod_rewrite seems to behave differently when the
client connects to my VirtualHost and includes the port as a part of the
URL. i.e. <a href="http://xenial.localdomain" title="http://xenial.localdomain">http://xenial.localdomain</a> vs. <a href="http://xenial.localdomain:80" title="http://xenial.localdomain:80">http://xenial.localdomain:80</a>

With this RewriteRule, the redirection that I want (to my SSL VirtualHost
listening on port 443) is working just fine as long as the client uses
<a href="http://xenial.localdomain" title="http://xenial.localdomain">http://xenial.localdomain</a> as the URL:

RewriteRule ^/?(.*) https://%{HTTP_HOST}:443/$1 [R=301,L]

However, when the port is specified ( <a href="http://xenial.localdomain:80" title="http://xenial.localdomain:80">http://xenial.localdomain:80</a> ), the
redirect does not work as expected.

httpd 2.4.25-1.fc25 avoiding search permission errors across file systems Fedora 25 linux

postfix permission check reads link mode rather its target

In main.cf I have

removing SASL Authentication

When I first set up my home mail server I mashed several "postfix
recipies" to get my working system. Not knowing why, this line
made it into main.cf.

smtpd_relay_restrictions = \
permit_mynetworks, permit_sasl_authenticated

I have no need to relay mail from anywhere except my own network
and I don't authenticate for that. I do get 500-1000 daily attempts
to relay but because I never set up an SASL Authentication Server,
none can ever authenticate.

I'd like to get rid of the "permit_sasl_authenticated" setting,
perhaps rejecting relay attempts earlier.

Postfix 3.2.0 stable release

[An on-line version of this announcement will be available at
http://www.postfix.org/announcements/postfix-3.2.0.html]

Postfix stable release 3.2.0 is available, 20 years after work began
early 1997. This release ends support for legacy release Postfix 2.10.

The main changes in no particular order are:

* Elliptic curve negotiation with OpenSSL <= 1.0.2. This changes
the default smtpd_tls_eecdh_grade setting to "auto", and
introduces a new parameter tls_eecdh_auto_curves with the names
of curves that may be negotiated.

* Stored-procedure support for MySQL databases.

domain forwarding/redirecting

I need a way to forward/redirect emails to and from a specific domain and send them to a specific local email account. I need this based on the envelope sender - so regardless of one or multiple recipients (in the header), the email goes to one specific account. It looks like the access filter REDIRECT will work for inbound but I'm not finding anything for outbound messages.

Just need someone to point me in the right direction.

SPF, Postfix and majordomo

Hello,

As I know, Postfix-users mailing list uses majordomo.

Suppose sender domain has set SPF policy with list of IP addresses
from which mail can originate for their domain. When the user sends a
mail to a mailing list manager like majordomo, being a member of the
list, the sender will receive back the mail posted to a mailing list.

Apache configuration - DirectoryMatch directive: Error in regex evaluation

Dear all,

I am using Apache/2.4.10 (Debian). Following the Apache documentation, I am trying to configure my server using DirectoryMatch. I get the expected behavior concerning the directories I want to handle (only user whose name is the same as the directory name can access to the directory). However I cannot access to the parent directory ("/var/www/html/webdav/directories/” in the example below) getting an “401 Unauthorized”. Changing the dynamic ldap user “%{env:MATCH_DIRECTORYNAME}” by a specific user allows me to access to "/var/www/html/webdav/directories/”.

DNSBL, Spamhaus and postscreen filters

I was prompted from reading a recent post to check whether my postscreen
set up was picking up Spamhaus responses. Quick grep through my logs
confirmed that it was not. Seems I am in a bit of Bind (sorry for the
pun). If I use Google's DNS I dont get a response from zen.spamhaus.org.
If I use my ISP's DNS I will but my ISP also hijacks NXDOMAIN responses
as I was reminded last night when postscreen blocked everything. I am
now looking at setting up my own unbound server, but I wondered if there
was a quicker solution. Can I use the filter option to ignore those
hijacked responses?

SRS software for postfix?

:-)

I'm searching for a Sender Rewriting Scheme tool well integrated with
postfix. postsrsd seems nice and generally works nice however it causes

alternative solutions?

Question about milters

Good day everyone. I have a quick question about a milter that I'm using.
I'm running Postfix 3.x. The milter is called SNFMilter and it uses a Unix
socket instead of inet. My question is a general question about milters. Is
there a way to bypass a milter for authenticated senders who are sending on
posts 25, 587 and 465? I know I can bypass all of Postfix antispam for
authenticated senders, but that is not what I want to do. I just want to
bypass the milter for these outbound senders. Is that even possible? Thanks
for all and any help.

Encapsulate incomming bounce mail

Hello,

in one project I'm sending a bunch of status mails to a number of
different recepients. From time some of them cannot be delivered
(address changes, server misconfigurations, employment changes, ...).

The bounces from the mail come back to my mail server and should go to a
contractor of us managing the e-mail addresses. Now I forward the mail to
an email on their mail server where it arrives, but later it gets lost
somewhere when internal distribution is done.

Hi' i'm trying to use mod_proxy_ajp module with apache 2.4.25 and tomcat 8.5.11 on oel 6.8
even if i uncomment the line in httpd.conf file for enabling the module it don't seem to load, i read that i need to also activate mod_proxy module and that is done.

do you know if a bug exist that would made it unable to load.

Regards,

Stephane
