I'm seeing some higher levels of attempted logins from various sources. Are there any automated filters that are suggested? Or do I simply add a check_client_a_access and reference a manually maintained blacklist?
grep 'after AUTH' maillog make this list as check client access on custommer ports, not port 25 i block big abusers with static firewalling just not port 25 i see after AUTH on port 25, unsure what to do ? maybe postscreen can do samme with that as pregreet ?
