Awhile back douglis@MINT.BERKELEY.EDU (Fred Douglis) reported a problem with sendmail: >>We're experiencing a problem sending mail to an internet host >>(decwrl.dec.com) -- the symptom is that the mailer hangs for a long >>time and then complains "reply: read error", apparently in the phase >>just after it sends the body of the message. I heard that about the >>same time we started having this problem on Sprite, a small number of >>Suns running SunOS 3.2 had the same problem, and I was told that >>upgrading the kernel to 3.4 fixed the problem. This is why I believe >>the problem might have something to do with the TCP connection (since >>just about everything at user level is the same, but the kernel is >>new). We are apparently seeing this problem from the other side. Occasionally sendmail will go to sleep (waiting for input ?) during a SMTP session with another host which is trying to deliver a message to us. This occurs at different stages (HELO, MAIL FROM, DATA) of the SMTP session. Sendmail eventually times out, but the host on the other end apparently makes multiple tries during the timeout period with the same result. We're running v5.61 of sendmail with some fixes from comp.bugs.4bsd under 4.3bsd-tahoe on a tahoe machine. Anyone experiencing similar problems? Anyone know of a fix?
