Hmm... I'm using sendmail. Can you please tell me how I'd check to see if this is the problem, and how to change it if it is?
Try this:
% netstat -na | grep '\.25[ ]' tcp4 0 0 127.0.0.1.25 *.* LISTEN tcp6 0 0 ::1.25 *.* LISTEN
Or this:
% netstat -na | grep '\.25[ ]' tcp4 0 0 *.25 *.* LISTEN tcp6 0 0 *.25 *.* LISTEN
Note that there are two white space characters between the two square brackets -- there is a space character, and a tab character.
If you see output like the second example, then you have an MTA that is listening on port 25 on all IP addresses and interfaces, for both IPv4 and IPv6. If you see output like the first example, then it's listening on port 25 for the IPv4 address 127.0.0.1, and port 25 on the equivalent IPv6 address.
