Hi,
I have more than 10 years experience in configuring mail servers, working with components like Postfix, Amavis, Spamasassin, ClamAV, Roundcube, and with solid knowledge in SMTP, DNS, DKIM, SPF
For this bid I can configure your mail server to interface with Amavis, Spamassassin, ClamAV. Spamassassin can be configured to automatically learn to recognise spam mail using its bayesian filtering capabilities.
