Rich Siegel, CEO of Bare Bones, confirmed earlier this evening on the Mailsmith-Talk email list that Mailsmith will not be seeing IMAP support. In an attempt to lay to rest much oft-repeated rumors about the company's email client, Siegel said:

Since we released 2.1.5, an enormous amount of work has gone into Mailsmith. Much of that work is underneath the hood, toward supporting new features and improving performance & stability. The version of Mailsmith in which I am typing this message implements a great deal of what has in the past been discussed on this list.

Most of the rework that we've completed was started with IMAP support in mind. After several false starts on the whiteboard, however, we put down the pens and carefully backed away. Despite our best desires and intentions and efforts, Mailsmith is not going to support IMAP. (The FAQ has been updated accordingly.) So if you're one of those holdouts waiting for the next rev of Mailsmith to support IMAP, so you can switch over, you can stop waiting. I have never had much need for IMAP, so this is no big loss for me. Mailsmith remains my email client of choice, and despite temptation to switch to Apple Mail, especially with the new Leopard version on the horizon, I look forward to Mailsmith's next release with enthusiasm.
