How to setup an SMTP account in Postfix?
 

Hello,

I have Postfix running and can send emails without problem from PHP via the mail() command. However, I want to use that SMTP server with my Outlook also, as my ISP's SMTP seems to be unreliable.

How do I setup a single SMTP account with username and password that can only be accessed from a certain IP address so that I can use it for sending my email from Outlook?

I know I need to change something in /etc/postfix/main.cf but I couldn't understand much when going through the file.

Thanks a lot for the help! I really appreciate it!

Hello again,

Actually, I managed to solve this myself, by adding

mynetworks = 127.0.0.0/8, my.ip.add.ress

to the main.cf configuration file. The problem is that it just authenticates me by IP address, but I would prefer also using username and password for better security. How do I implement this? Can anyone help me out?

Search with postfix+smtp+auth you will get a lots of good how-tos. By configurating main.cf with saslauth this can be done.

Some starting points:

ok setting up a SMTP server is not a problem but do remember if you are using RHEL 4 then you will have to use dovecot or any other service for POP accounts otherwise you will not be able to get your mails by pop service.
