I host sites and email via a root server from 1and1.com that is running Plesk Parallel 9.0.1 on Linux 2.6.23.16-20080211a. Spammers keep hacking my server and sending spam to everyone on my server and the world. My server is now blacklisted and does a poor job of blocking received spam. This has been a recurrent problem and 1and1 offers no support since it's an unmanaged server. Any tips and suggested software to add would be much appreciated it.
Plesk Mail Configuration:
authorization is required: SMTP
DomainKeys spam protection: Verify incoming mail
SPF spam protection: Only create Received
SPF local rules: include:spf.trusted-forwarder.org
Names for POP3/IMAP mail accounts: Only use of full POP3/IMAP mail accounts names is allowed
Thanks,
Paul
