- Would you be able to explain to me how SMTP AUTH prevents virus relay that cannot be accomplished with POP-before-SMTP?
With POP-before-SMTP: You check your mail with POP -> you can then send mail for, say, 30 minutes, but so can viruses, from any computer behind the same NAT box even. With SMTP AUTH: Password must be supplied with every mail transmission, which means that viruses must steal it from you, which is far from impossible but at least presents an obstacle.
I see the argument. The objective here is to allow relay by Linux laptops running qmail which receive mail from Pine running on the laptops. SMTP server would have SMTP level virus and spam check to counter this problem.
Thank you.
