Francoise, Thanks for the help. I tried to "telnet listserv.opm.gov 25." I got back a line that said: "220 servfwDC.opm.gov SMTP/smtp-proxy Ready. " That looks to me like I'm NOT getting through. But, since I don't use telnet and I'm not familiar with the feedback, maybe it just says I got through servfwDC, and the "Ready." is the goodnews I want. What does "220" mean? Can you interperet? I'm afraid I'm pretty ignorant when it comes to SMTP routing and delivery. I have forwarded your message to the administrator of "servfwDC.opm.gov." From your message, it seemed to me that the problem was with servfwDC, not listserv. From what you can see is that a CERTAIN fact, or merely a possibility? Is it possible that LSMTP is not loading correctly on listserv.opm.gov? I checked SMTP-19990622.log. It says.... 22 Jun 1999 12:18:47 LISTSERV SMTP listener, version 1.0d 22 Jun 1999 12:18:47 Copyright L-Soft international, 1994-99 22 Jun 1999 12:18:47 Initialization complete. What would be the next diagnostic step? Thanks so much for your help. --Mike >>> Francoise Becker <[log in to unmask]> 06/22/99 04:38pm >>> On 22 Jun 99, at 14:30, Michael J.

There is an MX that routes mail for LISTSERV.OPM.GOV through servfwDC.opm.gov. I've just tried it, and it _is_ accepting mail for [log in to unmask], so that's a good sign. Next thing is to find out what it does with this mail. You should check the logs there. Ideally, it's best if LISTSERV accepts its own mail, but if it's behind a firewall, then that's not always an option. To test whether LISTSERV (or really SMTPL aka "the listener") is accepting mail, telnet to port 25 of the server and see if it responds. I can't connect, but that probably means it's behind a firewall. If you are on the same side of the firewall as it, you can try: TELNET LISTSERV.OPM.GOV 25 and see if you get a response. Francoise
