Michal Čihař - Blacklists consireder harmful

Blacklists consireder harmful

After my mailserver started to reject mails from servers where I want to accept mails, I decided to finally try to disable DNS blacklisting. Earlier I whitelisted some domains, but the list has grown too much.

I still use DNS blacklists as helping criterias for SpamAssasin, but being on blacklist is now not enough to reject legitimate mail. Let's see if spam amount in my mailbox will increase, but I doubt it will, other checks are also quite restrictive.
