Plain text email clients?

Can anybody point me in the direction of a plain text email client? I'm basically looking for something like Mailsmith, but the sticking point is that we're using an Exchange Server - which isn't supported by Mailsmith.

Anybody know of another that will give me what I need?

Thanks!

Exchange Server is not plain-text friendly. It automatically converts every incoming plain-text message to HTML before delivering it to the client.

Yes, read that again.

Maybe the Exchange admin can disable this conversion, but somehow, I doubt it.

You can compose in plain text, using Entourage or any other client.

Now THAT is interesting... why on earth would it compose in plain text and convert to HTML??

Anyway, I had always used Mail.app, and ran into problems with Exchange Server at my office. I recently switched to Entourage and have had 100% no problems with Exchange Server. I do compose in plain text, when it pops up that way - it depends on how the email was sent to me (when I reply), in plain text or HTML....

Yeah, I've found all sorts of ways to compose in plain text. Reverse engineering it the other way seems to be the sticking point. Basically, I'm looking for a way to test email list mailings that go to text-only clients, without having to get a separate email account through another provider just for that.

Suffice to say, the endeavor has made me less a fan of Exchange Server than I already was.
