(Seriously - if 95% of the mail out there is spam, then the top 4-5 MTAs are probably the ratware that's sending out the spam. Something to consider...)
http://www.mailradar.com/mailstat/ Some of the most popular: 1. Sendmail; (24%) 2. Postfix (20%) 3. Qmail (17%) 4. Microsoft Mail In all fairness, the ratware programs that send out spam are usually MUAs, not MTAs, [RFC2476]. "Message Transfer Agent (MTA) -- A process which conforms to [SMTP-MTA], which acts as an SMTP server to accept messages from an MSA or another MTA" SMTP server installs that do not accept mail from other servers might be MSAs but are not MTAs. (The default mail server installed in Fedora doesn't count as a MTA, unless reconfigured to listen on some network interface, because the default config only accepts a SMTP connection from a local MUA using network loopback.) -- -- -J
