Emails showing from host.myserver.com instead of mydomain.com

Question

included is the header results form yahoo message. You will see if there that is has server.realcashback.com.au but I need it to not be and to be from my server, is there any way to make it send as my domain.com instead of the server. The domain I want it sending from is not on the same server.

I am using PHP

Answer 1

Some mail servers will add the Sender: header if the From: header doesn't match its understanding of the message's originator. If you have control over your site's Exim configuration, I believe you should be able to turn off this behavior.

If you also don't want to be visible in the Received: headers, you are most probably in for a bigger change in how you send email. One possibility would be to outsource message sending to a third party; depending on your reasons for wanting to do this, that may not be acceptable, either.

By the way, it's pointless to try to set Return-Path, as that will be set to your envelope sender at the receiving end. Perhaps there is a way to set the envelope sender from PHP, too (in which case I guess your Sender: problem could disappear, too).

Answer 2

Ooo maybe I know what the problem is, the domain of the from address (incard.com.au) doesnt match the name of the server its being sent from (host.realcashback.com.au)

If the email address your trying to say its from doesn't match the server name, your email will most likely get marked as spam, and some clients, will show that the email really didnt come from a server called (incard.com.au) which is true in your case.

If you own incard.com.au then you need to change your nameservers to point all (or at least mail) traffic to the ip address that (host.realcashback.com.au) is on

If you already have done this, then your mail settings in your php.ini need to be changed to match the incard.com.au address

SMTP = incard.com.au
sendmail_from = [email protected]
