Restarting the mail client in safe mode, or just restarting it resolves the issue. Reducing the number of cached imap connections in the accuont from the default 5 to 1 imrproves the situation but does not cure it. Cannot reproduce the problem on sites using the same mailserver which are not behind a PF gateway. I believe that PF has killed the cached connection, and when TB tries to talk through it, it patiently wait for an answer. I've looked at the set timeout option value directive for pf, but cannot determind it is what I want. Will changing the "interval" or "src.track" likely help my situation if I am correct in thinking that it is PF that is killing the cached connection before TB has finished with it? Lisa.
