SMTP Server for iPhone

Posted October 29, 2013 5.4k views
Hello, I want to create a mailserver on CentOS 6. It should only send emails, not receive. A user with account '' & '' can use the server. A user with account '' may not use the server. A machine with IP can use the server. All other IP's may not use the server. Does anyone has a good tutorial for this question? I hope someone can help me on the way. Thanks.

Take a look at postfix. It's a bit of a bear to configure, but it'll do what you want it to do.
I've already looked at postfix but I can't find any good tutorial for the thing that I want.
I'm searching for something that 'starts from the beginning'. Including configuration for the DNS servers (I already set those up but need to know how to configure the records for mail).
The DNS servers are separated from the mailserver.
yum install postfix
No DNS configuration required/needed, and it only sends... and you can make any email with it.
But I have to setup the mail in an iphone like: port 857.
so need to point to something right?
Why not make a simple php contact form so you can send from your own web page, but like sending an email! :)
No its has to be with a mail server :)
