Pine
I’m not typically a UW-IMAP person (yeah, yeah, “oh, this stuff again”) but I am really enjoying the novelty of using Pine on top of Slackware (and Windows, for that matter) to read my IMAP e-mail from a text client. In some ways, it seems like e-mail is still best presented in this form, especially the IMAP model. The concept of “expunging” is not easily depicted in a GUI. As purged as I feel I am from the MS Windows way of looking at the world, the “why the heck did that not actually delete?” question arises at times when using Thunderbird.
Dang, that was a long paragraph. Luckily, there is nothing else to say about this terribly dry topic.
