It's definitely not there. This has me completely perplexed. You seem to be doing everything correctly, and all of the right things are appearing in the sendmail.cf file, but the fault is definitely occurring. All I can conclude is that there is some trivial boo-boo somewhere that will have you slapping your forehead and shouting D'Oh! in the approved Homer-Simpson-esque style. It's going to be something on the level of you're not using the sendmail binary you think you are, or it's not reading /etc/mail/sendmail.cf. Have you sanity checked /etc/mail/mailer.conf ? Does anything untoward appear in /var/log/maillog ? How about the maillog entries when you restart the MTA? Can you try this: run sendmail in address test mode: % /usr/sbin/sendmail -bt and check the output of dumping the mailer definitions: =M (ie. make sure that the local mailer definition being used by sendmail is actually the same as in /etc/mail/sendmail.cf) Also try: /parse [EMAIL PROTECTED] which should give you Parse1 and parse lines like so: Parse1 returns: $# local $: david parsereturns: $# local $: david indicating that your sendmail will use the local mailer to do the final delivery.

The prog mailer is generally for aliases that pipe mail into programs -- eg: msgs: | /usr/bin/msgs -s It's not often used --- too much opportunity for abuse over the network. About the only thing I remember ever using it was majordomo, but I suppose it could be something to do with anti-spam or anti-virus scanning. The question now must be why your system is using the 'prog' mailer to do final delivery of your e-mail? Got any interesting entries in /etc/mail/mailertable or /etc/mail/aliases ?
