I added this line to my sendmail.mc file: DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl and additionally uncommented this line DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl Things are working like a charm now. I wonder, however, if that first line causes any possible security risks? I'm having quite the time finding much on this particular issue on the net...get a lot of sample sendmail.mc files in a Google search...but not anything with answers about this particular port part. If anyone knows of a security risk with this, please let me know! THANKS for the help all!
