I recently had this message pop up in my /var/log/messages when setting a new ISP up:
Oct 12 10:11:53 members sendmail[10720]: RAA31186: to=newwave@isp.com, delay=17:04:58, xdelay=00:00:00, mailer=local, stat=Operating system error
I was going to post here asking for help, but then found the problem: sendmail was looking for /usr/local/bin/procmail to exist, which it didn't. I found the info for that in /var/log/syslog. On a "whereis procmail" I found that it existed in /usr/bin/procmail, so a simple "ln -s /usr/bin/procmail /usr/local/bin/procmail" fixed it. Figured it might be useful to other sendmail newbies.
