Q380 I just got a “message not delivered” service message from the WL2K Common Message Server. Why?

100 Winlink 2000 -- General

A380 The WL2K outbound e-mail (SMTP) client will try and send your outbound mail directly (no relays) to the end recipient 10 times over a period of 5 hours. If it still fails (in this case because it appears the recipient's ISP is not accepting or blocking the connection) it gives up and sends a failure notice to the originator.

Most of the time these failures are due to:
(a) Improperly listed public MX record for the destination domain
(b) Some form of spam or other filtering mechanism used by the ISP
(c) The server is off line or otherwise down. If multiple servers for a
domain are available (as listed in the MX records) all are tried.
