Postfix some one spamming through my server. Help needed!

[SOLVED] Postfix spamming through my server. Help needed!

Hi, I have ISPconfig 3 by perfect server tutorial. Today some one starts spamming through two email boxes on server.

I changed passwords to mailboxes and spam still goes.
Mail box is for example [email protected]

Code:

When I renamed mail box than messages still are sended:

Code:

267B7308476     6267 Tue Dec  2 14:21:42  MAILER-DAEMON
(temporary failure. Command output: /usr/bin/maildrop: Unable to create a dot-lock at /var/vmail/citroenuh.cz/horsakova/23355.0.my.server.tld.)
                                         [email protected]

 

I don't wanna anticipate but I think, Till you are my heroe again.

I restarted postfix before, but I think restarting saslauthd make my day!

 

And again thanks, for explain! I was like :-O when i saw that deleted user sending emails!
