After the generally positive feedback that I got for the first few steps with my prototypical IMAP client, I put further effort into it, and implemented cool features like replying, group-replying (aka "Reply All") and sending mails. Currently, the only transport protocol implemented is SMTP, but I made everything as generalized as feasible, so replacing SMTP with e.g. the local "sendmail" command wouldn't be much of an effort. In addition, I added (hear! hear!) support for showing threads. This means that threads of email discussions, be it a long conversation between you and a friend or a discussion on a mailing list, is shown in its structure. Again, I compiled a feature show of new features since the last posting as
screencast.
