It's default has been 5 connections since for as long as I can remember
that option being there, and we've been using TB exclusively in our
office since about version 0.9...

I don't think this is accurate... I say this because I recall a problem
a long time ago where I had to decide between lowering the number of TB
connections, or raising the max per IP for the Courier IMAP server we
were using at the time - I chose the latter (change it in one place
rather than many dozens)...

Whether or not this will work depends on the environment...

I think what matters is that the number of connections that TB is
expecting to be able to use be *less* than the max supported by the IMAP
server. I do know that as soon as I changed the MAX number of
connections per IP in Courier to 5, all of our problems went away.
