At my server (5.9.158.75) I do just have a ssmtp agent which is configured to just move local mails to an IMAP account. Therefore I do wonder why spamcop complaints about my ip address to my ISP in this mail.
Any hints ?

Run an open relay test on your server. Hints. Your box may be hacked.

No external tools nor my test shows anything open at port 25 or so.
