I would like to customize the errors message with a little more verbose text that can describe in more understandable terms what the problem is and possibly list a URL reference.
ie, instead of: 554 Client host rejected: cannot find your hostname, [1.2.3.4] I would like to see something like: 554 Client Host Rejected. Your mail server's IP address [1.2.3.4] has failed one of our reverse lookup tests. Please reference http://www.example.com/errors/554-01 AOL does a nice job of this in their error messages and I would like to do similiar. Anyone have an idea where errors can be changed. I know for the specific tests in regexp we can specify errors but for these I could only find where to change the error number (ie 554) in main.cf. Thanks, Kevin
