Yes, there is no mx record for my ISP's outgoing SMTP server.
Should there be one ? It seems that only domains that are actually
having mail delivered to them should need an MX record.

The way that /mail/lib/remotemail invokes upas/smtp,
it is giving smtp.cox.east.net as the domain to deliver
the mail to. If the mx lookup returns zero entries
then it dials the name directly, but if the mx returns
a dns failure, then it waits for dns to unbreak.
You could change /mail/lib/remotemail to say
exec /bin/upas/smtp -g $addr -h $fd $addr $sender $*
(e.g., add the -g $addr option) and that should
dial the given address even when dns is failing.
Otherwise, edit /sys/src/cmd/upas/smtp/mxdial.c
is where to start, as Erik said.
