Anyone else have probs configuring IMAP mail account?

[bobmct]

One of the primary reasons for getting my Incredible was to integrate my business email. However, no matter what I try I cannot get my account to authenticate. Using a telnet app on the phone I can connect to port 143 on my mail server and authenticate but NOT with the built in app. I can, however, access my personal email on the same server and gmail.
Has anyone had any difficulties with IMAP and if so, what might have been done to overcome that? Thanks

I use K-9 (free in The Market) for IMAP and it works great (even with gMail). I no longer use the stock gMail client.
