I've just removed rmlsmptd and I'm trying to get the people with the remote machines to test (no Windoze in the office ;). It is quite a conincidence that this all started yesterday, just as MAPS switched.

Well, telneting port 25 from machines on the local network is fine, but I have been unable to test telnet from remote dial-up machines. Our upstream (Worldcom) hasn't said anything about starting to control outbound SMTP, and I think they'd let us know if they did (I'd hope).

The qmail server is on a dedicated 128K ISDN; the dial-ups are directly to the qmail server. However backlogged qmail-send gets trying to send out mail, it should be able to establish a connection with a dial-up machine trying to pass it mail, no? Otherwise, why have a queue? Thanks to everyone for the ideas.
