I just did an update from 6.0.8 to 7.0.0 on Ubuntu 8.04 64bit.
The update itself ran through without problems. But now I'm facing the problem that I can't receive any mail.
In the log I get errors like
I checked my server settings on zimbraMtaMyNetworks setting it to something like
NOQUEUE: reject: RCPT from host1[126.96.36.199]: 554 5.7.1 <email@example.com>: Relay access denied; from=<firstname.lastname@example.org> to=<email@example.com> proto=ESMTP helo=<host1>
Then I tried 'postfix reload', restarting the server but when I do 'postconf mynetworks' I'm never getting the same as set on zimbraMtaMyNetworks (something like '127.0.0.0/8 188.8.131.52/27).
Is there something else I can reset to have postfix pick up the correct IP addresses?
