SMTP Server for iPhone

  • Posted October 29, 2013


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.

No its has to be with a mail server :)

Why not make a simple php contact form so you can send from your own web page, but like sending an email! :)

But I have to setup the mail in an iphone like: port 857. <br>so need to point to something right?

yum install postfix <br>No DNS configuration required/needed, and it only sends… and you can make any email with it.

I’ve already looked at postfix but I can’t find any good tutorial for the thing that I want. <br>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). <br>The DNS servers are separated from the mailserver.

Take a look at postfix. It’s a bit of a bear to configure, but it’ll do what you want it to do.
