postfix is a better solution as the configuration a quite similar to sendmail We have it working as an smtp relay server Quite robust ----- Original Message ----- From: "Donald Burr of Borg" <dburr@borg-cube.com> To: "FreeBSD Questions" <freebsd-questions@freebsd.org> Sent: Sunday, September 08, 2002 03:05 AM Subject: SMTP AUTH support in sendmail? > Hi folks, > > Recently I had a bit of a dilemma.
