This may have already been resolved, but I had problems running the
sendmail program that came with the Slackware 2.0.2 distribution. The
problem was the sendmail server would hang during incoming SMTP connections
and while processing outgoing mail. I obtained the source code for sendmail
and traced the problem to calls to fsync in subroutines collect.c and queue.c.
I have Linux installed on a DOS partition using the UMSDOS filesystem, which
apparently does not support fsync. I deleted the fsync calls and re-compiled
sendmail and it now seems to be running normally.
Thought I'd pass this along.
