Hi Guys,

the other way around.
Yes, they are right :
Feb 1 21:26:42 mail postfix/pipe[19788]: D9A6D148050:
to=postmas...@ddblocal.com, relay=dovecot, delay=5.6,
delays=5.6/0.01/0/0.03, dsn=5.1.1, status=bounced (user unknown)
dovecot bounces message status=bounced (user unknown)
userdb:
driver: sql
args: /etc/dovecot-sql.conf
You din't provide contents of /etc/dovecot-sql.conf. Message is bounced
as dovecot can't find postmas...@ddblocal.com in mysql database.
There is something wrong with configuration in /etc/dovecot-sql.conf or
mysql database itself.
Here's my dovecot-sql.conf:
driver = mysql
connect = host=localhost dbname=postfix user=dovecot password=secret
default_pass_scheme = MD5
user_query = SELECT '/home/virtualmail/%d/%n' as home,
'maildir:/home/virtualmail/%d/%n' as mail, 150 AS uid, 12 AS gid,
concat('dirsize:storage=', quota) AS quota FROM mailbox WHERE username
= '%u' AND active = '1'
password_query = SELECT username as user, password,
'/home/virtualmail/%d/%n' as userdb_home,
'maildir:/home/virtualmail/%d/%n' as userdb_mail, 150 as userdb_uid,
12 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1'
when we transferred office, issues arose, suddenly users using email
clients like thunderbird/outlook suddenly can't send mail when outside the
office and instead gets an smtp denied
If you use Dovecot SASL in Postfix to authentificate the users it fails to
too... this is why you got smtp denied errors. Relay rulues prevents
unauthentificated users to send messages.
Check your userdb configuration an MySQL database itself.

I just looked at your previous messages... you had earlier sent the output of dovecot -n that showed version 1.0.7... was this your failed upgrade attempt? Anyway, are you using cyrus-sasl or dovecot-sasl? I'm not sure what exactly does it do, do I need to turn on saslauthd? It's currently not running. Only if you're using cyrus-sasl... I've also tried to upgrade via yum, almost broke it because before I was able to recall that I've rebuilt in from source. Try upgrading from atrpms/net repository... -- Best regards, Charles

[Dovecot] Mail undeliverable error
Hi Guys, I've already posted this to the postfix mailing list and they made sure the error as the title suggest was generated by dovecot and not the other way around. I have an almost perfectly working multi domain mail server running dovecot+postfix+mysql+postfixadmin behind pfsense, when we transferred office, issues arose, suddenly users using email clients like thunderbird/outlook suddenly can't send mail when outside the office and instead gets an smtp denied or worst a mail undeliverable error. The mail undeliverable error was that the postmaster user is unknown yet I've created the alias using postfixadmin. I've made repeated test and sent mail directly to the postmaster and the email was received by the intended user, I'm stumped and have no idea to fix this. Hope you can help me, TIA.
