Stopping acceptence from unowned networks address as from my domains

I got this email, which I thought I set up postfix to block

Multiple Virtual Domains


I have a new domain on my server and I want certain accounts to
be sent out with the new domain, rather than the default. I have it
set up at the moment so that any domain that you try to send though
get rewritten to the default, But I'd like this new
domain to be allowed through.

I'm sure this has been asked a few times. It just seems this mailing
list in not well listed by search engines any longer.

logging just stopped

I did some upgrades with opensuse this week and suddenly on 10-30
all the logging just stopped, and it seems not to be in journalctl either

The last messages were

Postfix Mailman integration


I have been running majordomo for a decade+ with postfix with no
trouble but I resently turned over to mailman and it is taking
3 hours to turn over messages. And I don't have this problem
with normal email, just when I use mailman. DNS is running on the same machine.

What can cause the list mail to hang for 3 hour or more?

majordomo postfix combination troubles

I've been using postfix with majordomo for years and it suddenly stopped working after an upgrade, and I can't shake down the cause of the error yet.

white list

WHat are some suggsted methods of whitelisting with postfix.

I am throwing in the flag and want to prevent email to me without my
specific permision, and to bounce the rest.


Restricting From Domains


I thought there was a means to restrict and/convert all the outgoing
mail that passes though postfix to specific domain names. I've noticed
that on several postfix installations that the sending domain name in
the envelopes From can be changed to almost anything. How do I
restrict it?


I used fetchmail to retreive email from the university and it hands off
the local system which cause the mail to try to be forward to

I'm trying to install the C++ connector as outlined on this URL:

How do I get postfix to reject mails "From" my own domains coming from
outside the local network?

Postfix Majordomo problem


I have this puzzle that I can't figure out. I had my mailing list
working on openSuSE 11.2
with postfix and majordomo. I've been using majordomo on sendmailf or
years with no trouble.
I moved to postfix with no trouble and now, suddenly I'm getting nothing
through to my lists.

I know this might be a majordomo problem but I'm not getting any useful
debugging information. And I see that the list is using majordomo
as well, so maybe someone can help me. I did test a change in the
majordomo alias to a testing program I wrote in perl and tha alias
seems to work.
