Nope, we don't have sendmail set with connection limits. sendmail logs
a bunch of lines like:
Jan 14 15:59:23 sh1 sendmail: NOQUEUE: SYSERR(root): getrequests: accept: No route to host
after the connections are refused sometimes (even when connecting from
the same system). Also, the monitoring program that checks dns, web,
smtp, pop3, ftp, and telnet on this server almost always reports a
problem connecting to FTP and SMTP at the same time (FTP is wu-ftpd, run
out of inetd, SMTP is sendmail running in daemon mode). But no other
types of connections ever fail that I can find.
