The Norton Antivirus application which is a desktop application AFAIK
does not distinguish between the ports. But maybe that changed
meanwhile. Just test it.
DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl
in sendmail.mc enables the submission agent with authentication
enforcement. I guess you have
FEATURE(`no_default_msa',`dnl')dnl
set - recommended - and thus the normal (not requiring auth) MSA
disabled. Setting the DAEMON_OPTIONS for the MSA be sure you have too
DAEMON_OPTIONS(`Port=smtp,Name=MTA')dnl
set - either this way or when restricting to specific IP, then several
lines of that with IP specification where 1 is for 127.0.0.1.
