Somebody else recently used some howto from there and had no end of
troubles.

eh? that says you did not log in pop3,  and postfix by default will
relay for localhost, well, with most configs in  mynetworks having
localhost it will.

telnet mail 110
user username
pass password
list
quit
... does that work? I bet it doesn't.

dovecot -n   output is best

you use sieve below, but now in proto?

verify your sql is valid by using mysql shell

You need to check your postconf -n   output as well to make sure it
knows dovecot.

postconf -a    should show dovecot (maybe cyrus as well, but it needs to
know dovecot)

If you followed whatever guide it was in full, and have triple checked
that, ummm, find another guide?
