Hello,

I just bought a dedicated server and I'm trying to install a webserver on it. The server is Ubuntu 10.04. I installed ftp, nginx, php, mysql, bind and now I have to install mail server.

For the mail server I'm using Postfix, because it's recomended on ubuntu.
I installed Postfix with apt-get install postfix but mail() function from php wasn't working. After a little debug I found the way to solve this : I created an empty file /etc/postfix/main.cf and it worked good.

I do have a mx record like this

mail                5M IN A     xxx.xxx.xxx.xxx
example.com.        5M IN MX    1 mail.example.com.

After that I wanted to forward all e-mails to my GMail address. So I googled for it and I found in the official docs Virtual Domain Host Forwarding

I added these lines in main.cf

virtual_alias_domains = example.com
virtual_alias_maps = hash:/etc/postfix/virtual

I created map file and I placed this line in it

@example.com [email protected]

I run in terminal

postmap /etc/postfix/virtual
postfix reload

The result: I can send e-mail from php with mail() function, but when I send an email to [email protected] that e-mail isn't forwarded to my Gmail.

How to solve this?

I also tried this but not working http://rackerhacker.com/2006/12/26/postfix-virtual-mailboxes-forwarding-externally/

It works now! But I don't know what the problem was. I just installed "Mail Server" from Tasksel and after that it worked fine. Can anyone tell me what Tasksel installed or that it changed ?
