I'm using Postfix together with Mailman to handle mailing lists on one of my servers. There is a delivery method defined in Postfix to handle incoming mail for mailing lists, "mailman". This delivery method is used for two domains, on which only mailing lists are hosted:
- charmides.phl.univie.ac.at
- lists.girlsrock.at
Setup for both domains is, as far as I can tell, identical. Yet, while mailing works for charmides.phl.univie.ac.at work, it doesn’t for lists.girlsrock.at. That is, if and only if emails are injected via SMTP, Postfix replies: “Recipient address rejected: User unknown in relay recipient table”.
The Error in Detail
root@menon:/etc/postfix# telnet localhost smtp
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 menon.phl.univie.ac.at ESMTP Postfix (Debian/GNU)
helo localhost
250 menon.phl.univie.ac.at
mail from:<root>
250 2.1.0 Ok
rcpt to:<postmaster@lists.girlsrock.at>
550 5.1.1 <postmaster@lists.girlsrock.at>: Recipient address rejected: User unknown in relay recipient table
However, the following works; that is, it sends an empty message to postmaster@lists.girlsrock.at:
sendmail postmaster@lists.girlsrock.at
By contrast, there are no such problems with charmides.phl.univie.ac.at:
root@menon:/etc/postfix# telnet localhost smtp
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 menon.phl.univie.ac.at ESMTP Postfix (Debian/GNU)
helo localhost
250 menon.phl.univie.ac.at
mail from:<root>
250 2.1.0 Ok
rcpt to:<postmaster@charmides.phl.univie.ac.at>
250 2.1.5 Ok
To the best of my knowledge, both configurations are identical.

The difference in their DNS replies is, so far, the only difference that I can make out. I’m not sure why it matters, though. I added an MX record for lists.girlsrock.at, but the changes haven’t yet propagated to my server.

Help!
I’m at my wits end, help is very appreciated! Does anybody have any idea what’s going wrong?
