I have followed your suggestion - not to the letter, but in principle, as I migrate across archs and hosts. First, I impersonated mail.cruwe.de setting hostname and /etc/hosts. Then, I sql-dumped and reimported the pgdb; then rsynced the postfix-configs. I changed the configs where IPs were concerned and checked delivery for c...@mail.cruwe.de - that worked. I then added a test@muellerbackwaren.local account, which I could have mail delivered to via dovecot and virtual maps. Worked too. Pruning all mail.cruwe.de-entries from the DB and switching the impersonification back to the correct mail.muellerbackwaren.local did no harm, dovecot continued to deliver. Step by step, I then tried to adapt main.cf to the new server and found the culprit in mydomain = cruwe.de. Changig mydomain = muellerbackwaren.local leads to Jul 8 22:08:42 mail postfix/smtp[1878]: B2BB713E4: to=<cjr@mail.muellerbackwaren.local>, relay=none, delay=0.14, delays=0.02/0.08/0.04/0, dsn=5.4.4, status=bounced (Host or domain name not found. Name service error for name=mail.muellerbackwaren.local type=A: Host not found) When I add muellerbackwaren.local to /etc/hosts (it has only mail.muellerbackwaren.local at this point), I get instead Jul 8 22:09:28 mail postfix/local[1999]: 144761410: to=<test@muellerbackwaren.local>, relay=local, delay=0.97, delays=0.54/0.03/0/0.4, dsn=5.1.1, status=bounced (unknown user: "test") That is were I was before. How can I, without having a named to nameserve proper domains, change main.cf to reflect that I am, in fact, catering mail for muellerbackwaren.local as $mydomain? Anyways, thanks for that slight ruffle of yours in calling me to discipline ... at least I now know how I have come to that erronous state. Cheers, -- Christopher TZ: GMT + 2h
