I have set up a whitelist on their email server to dump everything except for legitimate email addresses, however their host is not able to do the same and is having to forward all of the messages to their ISP for collection.
There are four alternatives;
- Change the customers domain name. This may be the only course of action to stop the influx, however will involve a fair amount of disruption to the customer.
- Set up a free address with Google mail for example and point the hosts mx record to Google.
- Set the mx record with their host to point to their internal mail server. This will most likely saturate their bandwidth and server.
- Transfer the domain elsewhere, and point the DNS 'A' record (website) back to their original host.
I'm waiting for instructions from my customer and have asked them to make direct contact with the host.
