Guys, Got a problem that I have reproduced on multiple sites, each time with windows clients, xp, win7 and win8, each time with Thunderbird accessing an IMAP server, which I have reproduced on my own site with win 7, but can't reproduce with my debian icedove mail against the same server. symptom - everything works fine initially, but after a period, when a user clicks on a new message, the mail client sits there for a very long time before loading the message. 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.
