Okay... I just reinstalled 4.5. I touched nothing on the system. I installed mutt through pkg_add, then created a 1M empty file from /dev/null.
I sent this email to myself thusly: mutt -a 1megfile m...@myaddress.com </dev/null Same exact behavior. It spools, then I have about .5 - 1 second before then entire system locks up. Again, I made no changes, with the exception of adding mutt. So..... the only wildcard I can think of is that I am running this on a Xen virutal server (on Debian Lenny)... though I cannot see why this would make a difference, and there is no error output on Xen either.... Is anyone else out there running a sendmail server on an AMD64 platform with OBSD 4.5? I would like to know if this is a problem with my setup, or with the release, at least. (I doubt that is the case, but I don't have a free amd64 system to play with, and I would just like confirmation). Thanks. Quoting Chris <cjd...@brokensolstice.com>:
Okay, here is a weird one... I'm running OBSD 4.5. I am using it as a mail server, using sendmail 8.14.3. I rebuilt sendmail because I wanted to use smtpauth. So I put "WANT_SMTPAUTH=yes" in my /etc/mk.conf, and rebuilt according to the docs. All seemed to go well. I configured my sendmail.mc/sendmail.cf, and still, all seemed to go well. All my tests on sending emails were successful -- until I started sending emails with attachments. Every time I send an email with a large attachment (say 5-15mb). Tiny attachments go through just fine. On my email server, if I send an attachment with mutt (for example) to another email server, the file will queue in /var/spool/mqueue as one would expect. After about 1/2 a second, my server will lock-up, and be completely unreachable by network or keyboard. Furthermore there is absolutely no error output in /var/log/maillog or in /var/log/messages. This is replicable from another mua as well, I have tried this on Horde and kmail. The results are the same. I don't think I have anything wrong in my sendmail.cf, but, fwiw, here it
is.
I appreciate the help!
