Hi All,
Ok we got the strange issue with one of or reseller customers.
He used to have all his domains on 1 account on 1 reseller server.
Becouse of update to php5.3+ we moved on of his domains to another server.
Now if he sends from the new server an email to an email adres on the old server he gets the message bounced back with error
We have double check all the obvious stuff (also found on google) but cant seem to find the issue.
I also have to point out that this problem only happens when he sends to old server to external email address there are no problems.
What am i missing ?
