I tried pegasus mail before, but when I tried it, it didn't understand imap/tls or smtp/tls. So far, the only windows client I've found that does these two correctly is outlook/outlook epxress. Which is too bad, because I have to use windows here at work, and I'd rather use something else. :(
For me, by far the best POP3 client I have used is Eudora Pro for the Mac. If there was a *nix version I'd be very happy, but alas there is not. I have tried Evolution and I like it but it has too much that I do not use and it is a resource hog.
For Mac or windows users I always recommend Eudora. It does POP3, IMAP and supports TLS/SSL on regular and alternate ports. Has a very good filtering system, supports multiple accounts and has humour built-in (run context sensitive help and you will see what I mean). Oh, and Eudora in general can not be "used" to propagate mal-ware (not impossible, just harder by default).
