Re: [gentoo-user] Postfix config problem

Probably you are using strict rfc envelopes. You must test your mail server using openssl command directly (I expect that you use TLS AUTH at least), do the full SMTP conversation with your server, EHLO, STARTTLS, AUTH, MAIL FROM, RCPT TO, DATA. All of them and check status codes. this interaction will give you info useful to find the trouble.

Can you test using the submission service?

Remind me of the command to do that?

"nano /etc/postfix/master.cf"

That was no help, so I tried:

mail –s "Test Email" prh@localhost
Cc:
Subject: Test
Test
^D

I got "Cannot parse address `–s': Malformed email address"

...so I tried with my address here: pe...@prh.myzen.co.uk and got the same
error. I even specified /usr/bin/mail -s ... and got the same again.

Perhaps Dale is right, and it's just not worth the trouble to run a LAN mail
system.
