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... > Some time ago I did more than cursory testing and found that TBird > only uses 1 of the 5.

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)... http://kb.mozillazine.org/IMAP:_advanced_account_configuration > Anyway, since testing I force all my user TBird configs to a single > IMAP connection. No problems. 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. -- Best regards, Charles
