I am helping a friend with his system. As such things are not as I
would set them up. But just the same I can't figure out this
problem. So I come here seeking a second set of eyes on it. What is
the problem that I am not seeing here?

That illustrates the problem. My friend has SquirrelMail set up but
it can't send mail to the 127.0.0.1:25 via SMTP due to Relay Access
Denied. That's the actual problem. But of course I use swaks to
debug things. But the goal is to get SquirrelMail running. And I
think that is running again. Pretty sure it had been working.
Here is the main.cf file, which my friend has modified extensively.
Personally I would trim out the items that are the same as the default
values. I know, I know, I changed the actual domain names so that my
friend wouldn't be annoyed that I posted this information. But
otherwise it's all there. I prettied up smtpd_recipient_restrictions
a little as the default wrapping was not good.
Because smtpd_recipient_restrictions starts with permit_mynetworks and
mynetworks includes 127.0.0.0/8 I would expect that smtp on the local
host to 127.0.0.1:25 should be allowed. But instead it is the Relay
error.

The master.cf is the Debian packaged default version of the file and
there have been no local changes. Confirmed by etckeeper.
So what am I missing that I will be astonished I did not see myself?
Thanks! :-)
