Here's a commented/example sendmail.mc snippet for that: dnl Address masquerading. dnl dnl Making sure that all email that passes through my desktop's dnl Sendmail installation is masqueraded as coming from dnl `kobe.laptop', even if its original address is something dnl slightly different (i.e. `ftp.laptop' or `mail.laptop'), is ok dnl here. It ensures that address rewriting and translation through dnl `genericstable' will also work for all `*.laptop' host names. dnl dnl To make sure that remote hosts don't get a MAIL FROM address dnl from a hostname that doesn't resolve, envelope addresses are dnl masqueraded here too, and then get rewritten by `genericstable' dnl to real-world addresses. dnl MASQUERADE_AS(`kobe.laptop') FEATURE(`masquerade_entire_domain') FEATURE(`masquerade_envelope') dnl Rewriting the envelope-from address of all outgoing messages dnl through a `genericstable' lookup ensures that envelope-from dnl addresses seen by relay hosts are real, i.e. have an address dnl of `keramida@ceid.upatras.gr' instead of the default dnl envelope-from of `keramida@kobe.laptop' that Sendmail would use. dnl dnl This is required some times, to avoid getting bounces for dnl messages from ISP mail relays that are misconfigured or are too dnl strict about what can appear in a MAIL FROM command. dnl FEATURE(`genericstable', `hash -o /etc/mail/genericstable') GENERICS_DOMAIN(`kobe.laptop') FEATURE(`generics_entire_domain') Here `kobe.laptop' is my laptop's hostname, and I have enabled address rewriting for some local email addresses by: % cat /etc/mail/genericstable # # Address rewriting of outgoing email messages. # keramida@localhost keramida@ceid.upatras.gr keramida@localhost.laptop keramida@ceid.upatras.gr keramida@kobe keramida@ceid.upatras.gr keramida@kobe.laptop keramida@ceid.upatras.gr root@localhost keramida@ceid.upatras.gr root@localhost.laptop keramida@ceid.upatras.gr root@kobe keramida@ceid.upatras.gr root@kobe.laptop keramida@ceid.upatras.gr % You will have to use a similar setup to change the envelope-from and header-from address of the outgoing messages your mail server sends. - Giorgos
