When sending emails with PHP, (from looking at the logs) the from address is translated to 'webIDemail@example.com.
But when the email is delivered, the from address looks correct (mailbox@domain).
So here is the example from my log:
amavis: (02564-02) Passed CLEAN, <firstname.lastname@example.org> -> <sales@recipientdomain>, Message-ID: <20090331122742.9E66FF7C24F@websrv1.serverdomain >
So the server domain is not the same as the website sending the email.
I can't even see a reference of the actual domain.
some mail servers will not accept emails like this.
said: 550-Verification failed for <email@example.com> 550-The mail server could not deliver mail to firstname.lastname@example.org
But if it did a verification on the actual sender domain, it would be fine.
When using Outlook, it does not do this. The address is correct, even when looking at the log.
I had the same thing with ISPconfig2, just cant figure out what it is.
Any help would be much appreciated.
