Hi,

my server work 287 days without problems. But today problems started. We can't receive any email from gmail, yahoo, hotmail, we receive error which I mentioned at beginning of this post.

I try send from gmail where I receive error:
Delivery to the following recipient failed permanently:

     MyEmailadress@mydomainodIredMail.com

Technical details of permanent failure:

Google tried to deliver your message, but it was rejected by the server for the recipient domain mydomainodIredMail.com by mail.mydomainodIredMail.com. [xxx.xx.xx.x].

The error that the other server returned was:
554 5.7.1 <gmailfromwhichIsend@gmail.com>: Sender address rejected: Access denied
