One of our customers, who is a reviewer with a magazine, has the
following email-account with this magazine:
[EMAIL PROTECTED],
however she uses her company-address as from-address:
[EMAIL PROTECTED]
Now she sends me an email from the account she has with the magazine:
From: [EMAIL PROTECTED]
To: [EMAIL PROTECTED]
This mail arrives in my mailbox with:
From: [EMAIL PROTECTED] on behalf of
[EMAIL PROTECTED]
The mail-headers contain:
From: [EMAIL PROTECTED]
Sender: [EMAIL PROTECTED]
Return-Path: [EMAIL PROTECTED]
But, in the Postfix logfile I see:
[EMAIL PROTECTED]
This gives problems with SPF: mail from "@mycomp.nl" which does not come
from an email-server of "mycomp.nl", so it will be blocked.
Doing something analogous from gmail, works allright: in that case the
from-address in the Postfix-logfile is the gmail-address, not the
mycompany-address (also the
Return-Path header has the gmail-address).
So, what determines the from-address Postfix will use?
regards,
Kees.
