Hello all,
I got some troubles with an installation that stopped properly working.
If I try to send an email I got this error:
Nov  6 20:02:05 srv1 postfix/smtpd[6834]: NOQUEUE: reject: RCPT from tbjjbihbhcfh.turbo-smtp.net[199.187.172.57]: 550 5.1.1 <***HIDDEN***>: Recipient address rejected: User unknown in virtual mailbox table; from=<***HIDDEN***> to=<***HIDDEN***> proto=SMTP helo=<tbjjbihbhcfh.turbo-smtp.net>

and I've found on mail.log this too:

Before of that I had this error:

but after changing all tables/columns to utf-8_general_ci this warning gone.

Re: Problem with "transport_maps lookup failure"

You have below settings in your Postfix:

transport_maps = proxy:mysql:/etc/postfix/mysql/transport_maps_user.cf, proxy:mysql:/etc/postfix/mysql/transport_maps_domain.cf

Do below command return any result?

# postmap -q "user@your_domain" mysql:/etc/postfix/mysql/transport_maps_user.cf
# postmap -q "your_domain" mysql:/etc/postfix/mysql/transport_maps_domain.cf

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?

they doesn't report nothing.
I've increased mysql connections and added google dns server to the dns servers list, and now all seems working properly. mail.log doen't shows more warnings or errors.
Anyway this seems strange to me, becouse If this was a mysql problem, then I should had troubles with other services like the web.

Re: Problem with "transport_maps lookup failure"

Hi,
after upgrading dovecot and SOGo (to version 3.2.2)  this morning I get errors similar to the above:
Nov 24 09:08:07 lvps87-230-17-232.dedicated.hosteurope.de postfix/pickup[836]: 6038F3E1C7: uid=993 from=<sogo>

I executed the two commands you suggested, they report following:

[root@mail /]# postmap -q "sogo@mail.fortytwo.cc" mysql:/etc/postfix/mysql/transport_maps_user.cf
postmap: warning: connect to mysql server 127.0.0.1: Too many connections
postmap: fatal: table mysql:/etc/postfix/mysql/transport_maps_user.cf: query error: Success
[root@mail /]# postmap -q "your_domain" mysql:/etc/postfix/mysql/transport_maps_domain.cf
postmap: warning: connect to mysql server 127.0.0.1: Too many connections
postmap: fatal: table mysql:/etc/postfix/mysql/transport_maps_domain.cf: query error: Success
[root@mail /]#

I do not know whether dovecot or Sogo upgrade did this.

Any ideas?

Thank you Zhang,
you repeatedly save my life! Any idea what could have caused this? It was working like a breeze before the upgrades?
best regards

Re: Problem with "transport_maps lookup failure"

I have no idea, maybe SOGo performed too many sql connections? i'm not sure, you have to ask for support from SOGo team instead.
