For the last few months everytime we e-mail our clients using our client management system, we get probably most of them back containing the following:
Mail Delivery Failed - returning e-mail to sender.
Unroutable domain "aol.com"
Now this returns on all e-mail addresses, whether is has a hotmail.com e-mail or aol.com, or excite.com or even e-mails hosted on our servers!
Also I have just noticed that when people request a password change on our forums we get the e-mail saying the above error.
So bascially our clients are not getting any of our updates nor password changes.
I e-mailed EV1 servers, but they have yet get back to me.
Has anyone had this problem or knows what the problem is? Could it be a setting, we do have Amavis with CLAM Anti-Virus installed.
Thank you for your help.
