Greetings.
I just moved to Centos 6 a postfix/dovecot email server previously (left
for a long time, alas...) on Centos 4.
Right now:
the dkim configuration on the old server was not working with the new
versions of postfix etc.. So I temporarily disabled it (commented out all
relevant lines in master.cf)
email from the outside is received correctly, and delivered to the right
maildirs
outgoing email sent via webmail (with roundcube in case it matters) is
delivered
but if I try to flush the queue after restarting postfix I get one error
like this (even if dkim is now disabled):
postfix/qmgr[3601]: warning: connect to transport private/dksign:
Connection refused
and many errors like this, all from, AFAICT, messages in the queue:
postfix/error[3640]: D7C00A4E96D: to=<marco.fiore...@gmail.com>,
relay=none, delay=144677, delays=144677/0.01/0/0.14, dsn=4.3.0,
status=deferred (mail transport unavailable)
The relevant lines of master.cf, and the output of postconf -n are below.
Any help to figure out what happened/is still happening and fix it is very
welcome, thanks.
Marco
