Need Help Configuring Postfix

[iainnitro]

Greetings:

I am new to Postfix and need to configure Postfix to simply direct mail out from my box to my ISP mail server. It actually can direct incoming mail to my user, but this is not necessary as the box is not really a mail server. The purpose is to allow my PHP scripts to mail out (specifically Wordpress).

Thanks in advance for any help.

have you read through the postfix configuration files and man pages?

The config files are very intuitive !

man page

Config files:

/usr/local/etc/postfix/main.cf, Postfix configuration parameters
/usr/local/etc/postfix/master.cf, Postfix daemon processes

Thanks for the reply. I have been trying to do it via O' Reilly's definite guide and because I do better with examples of the file entrys. thought I would seek the help.

master.cf

127.0.0.1:smtp          inet  n       -       n       -       -       smtpd

add an entry for your IP ( keeping localhost )

main.cf
look at the following

• mydomain
• myorigin
• mydestination
• myhostname
• mynetworks
• virtual_alias_domains ( if applicable but i doubt it in your case )
• masquerade_domains ( if applicable )

run 'postfix reload' or restart postfix once these changes have been made

There are tons of sample configuration files in Postfix's FAQ.

Check out: http://www.postfix.org/faq.html#null_client

Two suggestions for a starting guide. Dated, but still helpful, Dan Langielle's FreeBSDdiary page http://www.freebsddiary.org/postfix.php

Other good one, Ned Slider's article on the CentOS wiki

http://wiki.centos.org/HowTos/postfix

Very brief, but to the point explanation of typical main.cf changes. Those won't be Linux/BSD specific, they're just postfix specific. (Much of the rest of it is about installation on CentOS, and configuring Dovecot.)

The config file option you are looking for is relayhost. Put the IP (or hostname) of the ISP mail server in there.
