I have setup the first email address for a new site "webmaster ATsaeportal DOT com" which works fine. I then created an alias "info" for the site and tried to send an email to it, but the following error occured: Delivery to the following recipient failed permanently: info AT saeportal DOT com Technical details of permanent failure: PERM_FAILURE: SMTP Error (state 9): 553 sorry, relaying denied from your location [18.104.22.168] (#5.7.1) I then tried to create a mailbox for "info" and then tested the account. But the same error keeps coming up. What have I done wrong? As I stated, sending anything to "webmaster" works just fine. Thanks.
