+ + +We had a Linux box dialing the Net and collecting mail from an NT POP3 +server. Fetchmail was correctly collecting and deleting each e-mail +one by one. However,the dial-up connection was very unreliable and +would often just drop out in the middle of a session.

+ +Interestingly, unless the TCP POP3 connection was terminated normally +(I guess with a POP3 "QUIT" command) NT would then roll back all the +deletes !!!

+ +This meant if the first e-mail was very large it might just end up +continuously collecting it, basically jamming the queue. Or, if the +queue became very full itmight never get a long enough phone +connection to retrieve the entire mailbox, and NT would roll back any +deletes, so it would end up collecting (and delivering) the first few +e-mails again and again. As the POP3 mailbox became fuller and fuller +the chances of getting a connection long enough to collect theentire +mailbox became smaller and smaller.

+ +Our solution was to make fetchmail only collect a few (say 5 or 10) +e-mails at atime, thus trying to ensure that the POP3 connection is +terminated correctly. + + +That's one solution. Perhaps a better one would be to FORMAT C: and +install Linux on your server...
