Funny you should mention that, I'm looking (tweaking) that file now. :)
Interestingly enough though. The last info I noticed about the delayed
logon. Was from Jan whom recommended that they get a slightly different
(newer?) version of Horde. I'm not suggesting that applies here. But
for some reason it stuck in my mind.
Anyway, thanks for the suggestion. Maybe it will help a little.
I'm still going to install Dovecot. I need a more modern, more
administrator friendly, less a hack IMAP server. :)

Thanks again.

Shameless self-promotion follows...
