What is the best mail program to use with fetchmail?
Fetchmail will work with all popular mail transport programs. It also doesn’t care which user agent you use, and user agents are as a rule almost equally indifferent to how mail is delivered into your system mailbox. So any of the popular Unix mail agents — elm, pine, mh, or mutt — will work fine with fetchmail. All this having been said, I can’t resist putting in a discreet plug for mutt. My own personal mail setup is sendmail plus fetchmail plus mutt. Mutt’s interface is only a little different from that of its now-moribund ancestor elm, but its excellent handling of MIME and PGP put it in a class by itself. You won’t need its built-in POP3 support, though; most of the mutt developers will cheerfully admit that fetchmail’s is better :-).
