I'd like to add, proceed cautiously. I've been running postfix on my external gateway for a couple of decades but recently migrated all but one of my internal machines from sendmail to postfix. There were a couple of hiccups along the way. In one case there was a mail loop of at(1) jobs which required the tweak of a procmail rule. In the second case nmh submits mail to localhost:587 requiring altering master.cf. nmh uses only that port though it can pipe directly to the sendmail binary when built that way. If dma doesn't support SMTP submission, we may need to review various port default options or whether ports even support it. -- Cheers, Cy Schubert <Cy.Schubert@cschubert.com> FreeBSD UNIX: <cy@FreeBSD.org> Web: https://FreeBSD.org NTP: <cy@nwtime.org> Web: https://nwtime.org The need of the many outweighs the greed of the few.
