Hi there, I have a question concerning ISPConfig > Monitor > Show Mailqueue There is something like this, if a mail is in queue: 195B5138C001 2584 Mon Dec 9 20:36:34 [email protected] I dont know the mailaddress [email protected], is this a hint that somebody sends spam from a account hosted on my server? What can I do? Thanks!
Check the content of the emails with postcat command. example: postcat /var/spool/postfix/deferred/1/195B5138C001
