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.

submission rate limit advice

I've tightened or rather overtightened several postfix limits, in what
seemed like a good idea at the time...

noticed now this warning, this user is on a dynamic IP, so can't add his
IP to exception:

going by the counter "Connection rate limit exceeded: 125", what values
should I alter?

Current ideas on DKIM signing ?

Hi,

Am currently refreshing my perimeter mail infrastructure.

The current state of affairs of DKIM signing looks pretty miserable!

DKIMProxy seems to be abandonware since 2010

OpenDKIM seems to be going the way of abandonware too (last release in 2015 and the bug tracker filling up).

I've had a quick search on github for DKIM but can't find much of interest.

We all know what software is like, you have to keep it fed and watered otherwise it starts growing bugs (or worse). I'm not too keen on using software of 2015 vintage.

What is everybody using these days ?

Visual Studio 2019

Here we go with the new Visual Studio 2019 download with APR 1.7 and
the warning fix from Ylavic

We call it now VS16, and it is backward compatible with VC14 and VC15

Question about configure not answered in documentation

I am guessing the answer to my question is probably "no", but I'm hoping
someone here has a silver bullet.

We are finally getting our act together and updating our Apache server instances.
Our chosen way to do this is as follows:

The /apps directory holds application software distributions, suche as

/apps/apache_2.4.25
/apps/apache_2.4.37
/apps/apache_2.4.39
/apps/apache (this is a symbolic link to the current distribuiton)

We keep the DocumentRoot directory outside of the distribution tree because
when we want to update the server, we don't want to have to copy the HTML
and cgi file

SPF and Greylisting

Hi,

policyd-spf and postgrey are implemented and working.

With exim, I was able to check the spf result and greylist upon receiving a
certain result. I'm using Mail_From_pass_restriction = mfrom_passed_spf in
policy-spf.conf.

Is there any way I can defer or greylist based on an spf result of Softfail?

True. But considering that Net::Milter also does the right thing, it seems like

Rewriting recipient before routing the email

Hello again,

Is there an option to rewrite the final recipient, to remove some extra
characters, with some header checks, for the incoming emails.

This is what I want to achieve:

For instance, if postfix receives emails for <a href="mailto: ... at rodier dot me"> ... at rodier dot me</a>, the
final recipient would be rewritten as <a href="mailto: ... at rodier dot me"> ... at rodier dot me</a>, and an
additional header would be added, for instance, X-Valid-Date: 0304.

Maybe I can do this with recipient delimiter, but can I have more than
one character recipient delimiter in postfix?

The idea I have in mind, and the first tests are promising, is to allow
my users to register on w

Bug report: problem with smtp_mx_address_limit = 0

According to the docs, the smtp_mx_address_limit parameter determines
"the maximal number of MX (mail exchanger) IP addresses that can result
from mail exchanger lookups, or zero (no limit)".

However, when setting it to zero, the SMTP client won't even attempt to

Authentication attempts for xxx@com.au addresses

Not sure if this is a Dovecot or Postfix issue we use Dovecot for authentication for Postfix. Mailboxes are stored in MySQL.

Have noticed this today:

Also <a href="mailto: ... at com dot au"> ... at com dot au</a> etc.

They are coming through on port 465.

Obviously my domain is not ‘com.au’ - how can I stop these attempts from even being considered?

I did update to Postfix 3.4.5 yesterday. Running Dovecot 2.3.5.

Postfix stable release 3.4.5 and legacy releases 3.3.4, 3.2.9, 3.1.12

[An on-line version of this announcement will be available at
http://www.postfix.org/announcements/postfix-3.4.5.html]

This update fixes 5+ year old bugs, and provides a Postfix 3.4 fix
for sites that depend on undocumented behavior.

Changes for all supported stable releases:

* Starting with Postfix 3.0, LMTP connections over UNIX-domain
sockets were cached but not reused. Therefore, idle cached
connections could exhaust LMTP server resources, resulting in
two-second pauses between email deliveries.

Combining SSL and basic user (group) authentication

Dear all,

I’m trying to figure out how I can give access to documents by combining SSL and basic user authentication. The following is from my httpd config:

AllowOverride None
Options None

AuthType Basic
AuthName "Test User"
AuthBasicProvider dbd
AuthDBDUserPWQuery "select human.get_user_password(%s);"

Require ssl
Require dbd-group user

The “Require ssl” denies access to the document for normal http:// connections which is what I want.

How to use the new server TLS SNI feature (3.4.x)

Hi,

I've noticed the release of the new SNI feature in Postfix 3.4, but I
cannot get a successful setup. My last attempt was to

tried encoding the certificate as base64 according to the documentation).

For reference, what I'm trying is to have a main certificate for the mail
server and another certificate (letsencrypt) for a specific domain.

Thank you,

how to check email delivered via MX backup host

Apache web server devouring resources

Gentlefolk,
I had an incident yesterday where the Apache web server host had a load average of over 170 and was performing very slowly. Stopping the web server did fix the issue but when I restarted the daemons the load started to increase very quickly. I ended up having to reboot the system to fix the issue. I don’t like that one bit, this is a Linux system not a Windows server. (Editorial remark: I have found that systems need reboots to fix stuff much more frequently since the adoption of systemd) I have been asked to do a root cause analysis, but I have not found anything as of yet.

I want to configure postfix such that I get log level 4 for specific ip or

In this case postfix is not providing all debug logs.(May be providing log
level 2 logs)

I was expecting that I will get debug logs of level 4 as we get when we set

Anyway, the next morning the sites utilizing PHP were getting a 503 error before we restarted anything.

permit_tls_clientcerts with CN matching

Hello,

we need to authenticate a SMTP client connection base on the CN of the
(trusted) client certificate. The client is not under our control
(O365 connector), so we will get no notification if the key
fingerprint will change. As far as i can see Postfix is only able to
use certificate fingerprints to allow relaying, not the CN string, no?

Have i missed something or is this not considered a valid use case?

difference between setting up an alias in virtual_alias_maps and virtual_mailbox_maps?

What is the difference between setting up an alias in virtual_alias_maps
and virtual_mailbox_maps?

I can make alias@domain point to a mailbox by pairing it with the path
to the maildir in virtual_mailbox_maps but it seems if I do that the
alias can only point to one mailbox not multiple.

e.g

user@domain     /path/to/user@domain/

alias@domain    /path/to/user@domain/

this works OK but if I was to do

user1@domain     /path/to/user1@domain/

user2@domain     /path/to/user2@domain/

alias@domain    /path/to/user1@domain/

alias@domain    /path/to/user2@domain/

this doesnt work.

nfs as mailq storage?

Hello

Is there a way for postfix to store its mailq on a nfs share?

And what do i need to change to make it store the q over there.

The nfs share is mounted to the postfix server in the fstab config file.

Case for this is, we are using postfix in a poc case for are vessel mail as= a relay host.

So when we have sat communication mail leaves the vessel on the spot, but w= hen we have not sat comm mail has to stay in queue until sat comes back.

Thing is when are vessel is in voyage on the ocean there are places where t= here is no coverage and mails get for long time in queue.

$queue_directory/private permissions

Hello,

I am running postfix (3.3.0-1ubuntu0.2) confined by Apparmor and I
noticed the tlsproxy process is apparently trying to connect to tlsmgr's
Unix socket while still running as root.

Since tlsmgr's socket is stored under $queue_directory/private that has
perms set to 0700 and owned by postfix:root, the tlsproxy process needs
to override the DAC checks using the CAP_DAC_READ_SEARCH capability.

I can think of 2 ways to workaround this.

SPF setup Temperror

Hello,

Dovecot 2.2.27
Postfix 3.1.9

I had SPF setup proper, originally. Then, it stopped working properly
after some other configuration changes, as I tried to go through and
eliminate errors.

Here is my header information.

Received-SPF: Temperror (mailfrom) identity=mailfrom;
 client-ip=167.89.106.69; helo=o1.31qt.s2shared.sendgrid.net;
 envelope-from=bounces+9243903-ab61-me=example. ... at em8306 dot emailtester.o
rg;
 receiver= ... at example dot com 

My two questions:

1. The Temperror. How do I turn that into a pass?
