First, I have a perfectly functioning Qmail 1.03 to the tune of about 20K messeges/day. So this is really a MUA question, but geez, remember we're talking about Microsoft here folks, get a straight answer?, unlikely. So this is a more "have you ever encountered?" Outlook Express 5 suddenly and for no apparent reason will talk to qmail-smtpd fine if the message is under about 300 bytes. Add a few lines, or an attachment and it just hangs until it timeouts and asks of the user want to wait longer. User has several machines attached to a 3com lan modem and they all behave similarly. Everything else over the connection seems to be working fine, including qmail pop3. Baffled.
