It’s common knowledge among GNU/Linux users that there is a significantly lower chance of being infected with malware when running GNU/Linux than there is when running Microsoft Windows; however, it would be wrong to say that there is a flat zero chance.
Malware does exist, although the odds of you stumbling upon it are low.
Never looked at F-Prot so have no comment other than maybe I'll take a peek. They are usually in applications rather than the kernel; since there is more separation than in Windows, bad things can be mitigated.
(google for Kevin Mitnick, sendmail bugs, DNS bugs, etc).

Combining these altogether results in a mail server with strong protection against spam and virus-infected mails.
Below are the procedures to setup the MTA (Mailer Transfer Agent) Sendmail.
