I found the bug. 15N2 introduces support for FAL-like mail, ie filetype of NOTE and RFC822 header. Thus, the error message is different with 15N2. The mailfile is successfully parsed, and LISTSERV complains that the gateway is not officially registered in DOMAIN NAMES. Since this may also happen to a user whose local mailer has not been registered, the message is sent to the sending user and the postmaster. After 10 times, the user gets SERVEd out. However, what gets served out is the NJE address (since the RFC822 one is illegitimate), ie [log in to unmask] What gets tested against the list of disabled users is the "From:" address, which is another form of the same thing (ie "[log in to unmask]" or something like this). I have added another test against the NJE origin. I sure wish there was a list of internet -> NJE node mapping, or even better, a tag in BITEARN NODES (but this would take 10 months to be agreed upon and another 2 years to be implemented). John: I sent you a fix (LSVRDR EXEC), you'll have to reboot and to issue a 'QUIET SERVE MAILER@SLACVM' (for other reasons - now it can't get served off any more, but this had not always been the case).
