Dear Team,
I have also been experiencing the same issues. Below is one of such messages:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:
[email protected]
all hosts for ‘ax101-7.gemmasmith.co.uk’ have been failing for a long time (and retry time not reached)
When i checked the request message header, it was requesting my ‘site login details’
How can i block this specific domain from registering or accessing the sit?
