my mail server currently is under dictionary attack - 5-6K of names per day, any ideas how it could be stopped?

Use iptables to drop any connection attempts from the IP range that is attacking you.

Unfortunatelly I'm not capable of doing this - I receive my mail via relay (and I cannot block the ralay) I'll try contacting the provider...
