hi!
I have a couple of real bad sender, sending hundreds of mails to a couple of accounts on my server. I already put their domain an the blacklist, but this only results in a very large number of quarantined mails 😉 Is it somehow possible to reject mails on smtp side directly if they are blacklisted or where do I have to place this domains? E.g. *@sampark.gov.in
Thanks in advance,
Patrick
