"spamholed" domains
I thing spammers are attacking that domain and it continues all the time.
They are sending dictionary attacks to that domain, I have tried to use EXIM tweak to block there but it is not possible because every days it gets traffic from different hosts.
How to fight with these? I don't wanna to terminate account because it is legit customer and he has nothing with this.
It is possible to stop all mail for this domain? I have tired to remove MX entry but it don't help.
Any bright ideas are welcome!
