I used to not be able to use Versamail with our organization's Groupwise IMAP server. I registered Chatter so I could use IMAP email. That worked great.

After the MR, Chatter now has horrible drag, and sometimes lockup, when calling Blazer from a link, or viewing HTML. It also sometimes loses knowledge of my SD card. That's a problem because my mail folders are stored on it.

I have configured Versamail again for our Groupwise IMAP server, and it works! It's not nearly as flexible or sophisticated as Chatter but it suits my needs fine.

GW doesn't support the idle IMAP command, so I can't use background synching even if I wanted to (which I don't). So switching to Versamail doesn't lose that for me, because I never used it.
