smtp mail stopped working

Tim Killinger — Thu, 01 Apr 2004 14:21:34 GMT

on my vms 7.1/UCX 5 machine smtp mail has stopped working (after years of no problems)... networking in general seems fine... I've enabled ucx log level to 5 and am getting the following in UCX$SMTP_LOGFILE.LOG:\

Entering build_server_mx_list
#smtp_sender_cmd\4348 Entering new_smtp_sender_gate
#smtp_sender_cmd\4372 new_smtp_sender_gate: SMTP zone = mcvlva.tel.gte.com

Also:
[UCX_SMTP]>ucx show mx

Local MX database

Destination Preference Gateway

No real idea, but if I try to deciper what I think could be a status code I get:

iosb$ext_st:
$ write sys$output f$message (8340)
%SYSTEM-F-UNREACHABLE, remote node is not currently reachable

Tim,

What is the outcome of:

$ TCPIP SHOW ROUTE/ALL

and try to locate the destination nodes (that is: both the mail gateways and the receiving nodes) by trying to trace them down (TRACERT, probably).

You may also try to DIG the domains (mcr TCPIP$DIG, I don't know if this exists in the TCPIP version, use TCPIP$NSLOOKUP instead)

Hi,

do a

tcpip show config smtp/full

Check the Gateways you have defined, then see if you can reach them (ping and traceroute being the first tests, followed by a telnet to
port 25). Is it possible that somebody has put a firewall up somewhere in the route between you and the gateway?

Greetings, Martin
