Sendmail - Masquerading multiple domains

Posted Tue, 01/26/2010 - 12:26 by MWalker

I have a little VPS that is used as platform for POP'ing and SMTP relaying for internal projects and testing.  Originally it was all setup under a single domain and I had turned on masquerading.  However I needed to add another domain for a different project.

Perl Script - Active Directory Password Expiration

Problem
