Catch-all setup not supported
Catch-all addresses used to be created to ensure that messages that were accidentally addressed to an incorrect email address for a domain could still be received.
Unfortunately, Spammers often try to guess email addresses in your domain; when they guess incorrectly, the spam is delivered to the catch-all address. The volume of incoming messages may well exceed the Gmail receiving limits, resulting in the account becoming locked or in legitimate messages being deferred, delayed, or bounced.
That is why HIS Has decided to stop supporting this type of email set up.
