This only means that LISTSERV has sent the mail to the outbound Mail Transfer Agent program (LSMTP in your case) this does not mean it has been deliverd to the final recipient's mail server. It does not even mean the mail has been received by the MTA. If you suspect problems with delivery to LSMTP, look for *.MAIL files in the x:\LISTSERV\SPOOL directory. If there are some, look in x:\LISTSERV\LOG\SMTPS#1-yyyymmdd.LOG file for clues to the problem (malformed addresses, etc). If none, then no problem there. Now look in LSMTP. Is there mail backed up in SMTP Entries in the QUEUE? If so, Show | Scheduled Calls | Full Display | Refresh and search for your problematic domains? >The LSMTP log file does not indicate any delivery errors. It doesn't normally record mail-specific errors anyway. Are you running Full Accounting in LSMTP? If so, the x:\LSMTP\LOG\acc_yyymmdd.dat file has a record of all mail successfully delivered. Grep it for the problematic addresses. If it is a '5' record it was succesfully delivered to receiver's mail server. If so, then the mail disappearance problem is on the receiving side. Still not sure? Use site-specific logging in LSMTP to record specific traffic to the problematic domain.
