some of my users are in china now and have problem checking their mail. Apparently the mail client (Outlook in this case) will just download mail until it halts halfway... then error showing that they were disconnected from the email server. My guess is the China connection caused them to timeout.. but weird thing is.. why would it be able to download mail until the same one before it halts... its happening to 2 of my users over there, though I am not sure (and doubt so) that its because of the same mail... saying that... what is the way i can trace or better still, rectify the problem. I'm thinking of some reason 1) Poor connection that causes timeout 2) A particular mail that causes it I've look through the log but don't find much.. or maybe.. i dunno what I am looking for. Is there anyway to increase timeout duration for POP? What does qmail use to send mail? Many thanks!
