We aren't using Solaris (but BSDi). What we ran into was a limit on the
number of processes (we think...when our old BSDi guru explained how to
increase that the problem stopped). We increased smtp_accept_max enough,
and carved out a nice big reserve for our customers to use, but then
customers were silently failing to connect to the SMTP server.

My guess is that you had your problem Thursday morning US West Coast time?
That's when we shot ourselves in the feet (hard to do with one shot when
the people doing it are 15 miles apart).
