i'm jumping in on this, as I have a similiar problem... using the postconf -n, I think i see my problem...... the mydomain_fallback is localhost, as is myhostname.

in checking the mailq it appears my mail is trying to go out with a email@hiddenhost sender address.

(i'm trying to use php mail to send out mail..... from a moodle installation)

so I guess what I need to know, is how to change the config of postfix to put my real server info in, rather than localhost.

mydomain_fallback is suppose to be set as localhost. Leave that alone!

myhostname is suppose to be the hostname of the server and this is where your problem is.

In Server Admin on the General Settings screen you should have your Domain name and your Host name set.

Example:

Domain name: example.com

Host name: host.example.com

When you send mail out using the php script it will be addressed as coming from email@hidden although I believe you can change that by adding some additional parameters to the script. Do a Google search on php mail() to find out how to change that but leave the server setting as it is suppose to be.

The mail server uses the host name for its HELO which needs to match your MX setting in DNS or at least have a corresponding A record if it's an outbound only server (not receiving mail).
