Mainly Pine. Then Balsa, because it use the same marks (read, answered, etc) as Pine does, and is able to display html and photos. For emails containing complex html or images, Mozilla or Netscape. Sometimes, Kmail, if I start kde (which is seldom, I'm afraid).
Well, I must have missed the original thread. Anyhow, here's my two cents worth. Currently I use Mozilla (1.3b) for mail on both my SuSE 8.1 desktop (POP3 mode) and my Win2k laptop (IMAP mode). I also use Pine if I'm away from my main machines and need remote mail access. In the past I've used Polarbar (java based - worth a look), elm (I prefer pine though), kmail and evolution (both very briefly), and ages ago I used Netscape 4.x for quite a while. -- John LeMay KC2KTH Senior Enterprise Consultant NJMC | http://www.njmc.com | Phone 732-557-4848 Specializing in Microsoft and Unix based solutions
