I cured the problem by creating a special rule enabling SMTP. At least the

computer is firewalled off from it? Why have email capability then stop it
from working? Only lawyers do anything so ridiculous. I was one - and
hated it for that very reason.
Doug - living inside a social firewall, a retirement village, "God's waiting
room."
Many, if not most, Linux systems to nightly cron jobs to rotate logs,
check for updates, scan for weird messages in the system logs, etc.,
etc. These are normally emailed to the cron job owner, who is normally
"root". The SMTP server is used on these systems to deliver the log
messages somewhere useful: the normal restrictive firewall does allow
that server to transfer the email *out* to a remote target, while
refusing all non-local email. On such a system, you may as well block
port 25 incoming, because nothing should be sending to that system
from elsehwere until you're bothered to turn it on.
Does that make more sense?
