postfix main.cf file

[Stephen]

Froxlor's instructs in the Configurations for

Debian 5.0 (Lenny) ? Mailserver (SMTP) ? Postfix/Dovecot

are to have in the file /etc/postfix/main.cf the lines

mydomain = froxlor.example.com

# should be different from $mydomain eg. "mail.$mydomain"
myhostname = froxlor.example.com

Where I have substituted my actual domain name with "example.com".

 

These lines would set the variables "mydomain" and "myhostname" to the same value which is contrary to what the comment says should be. Is this really correct?

[Dessa]

the hostname in that template is automatically replaced, then again, we can't autodetect everything, so the comments are there so people can change it to the correct value.

HOWEVER, it will work if you leave it like it is ($mydomain and $myhostname the same).

now if you wouldn't set myhostname, it would use example.com in that situation, which can be in turn managed by froxlor, which would most probably cause issues.

[Stephen]

Does this mean to avoid the most probably caused issues we are expected to change these values to something like this:

 

mydomain = example.com

# should be different from $mydomain eg. "mail.$mydomain"
myhostname = mail.example.com

?

Where the value of myhostname must be in the Bind9 A record for the mail exchanger?
