[Dovecot] Can not receive mail

[gdekeijzer]

Fresh install of:-
Ubuntu 12.04
Apache
Bind
Dovecot
ISPConfig3 (latest)
Added Roundcube as webclient

I setup DNS and mail for a client.
However mail doesnt arrive and sending mail from webclient (Squirrel or Roundcube) results in no repons.

The mail.log show an SSL_accept error.

Trying telnet localhost 25 doesnt give reponse.

Any suggestions?

Regards,

Gerwin

Hm, nothing happening.
Only i now have a TLS error.

This is the log from the moment i restarted postfix and trying telnet localhost 25 with

root@kuga:~# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
EHLO gmail.com
Connection closed by foreign host.
root@kuga:~#

as result.

So i suspect there's an error in my SSL certificate. Could this be the case?

Thanx.

Yes, probably. Have you tried to recreate it (accepting all default values)?

[gdekeijzer]

Hm, can you help me with the command to do that? or is that in your 'perfect server' guide ?

Thanx

[falko]

The cert is created by ISPConfig, so I suggest you just rerun the installation and accept the default values for the cert.

In dutch we say: The road with the least resistance.

I reinstalled the complete server (strange other behaviour).
Now working fine.
