But my client doesn't send spam, he just uses affected SMTP server (what I know, his mail provider is his ISP). Therefore I can't receive his email.

He at least needs to complain to his isp about the fact that people who he sends to can't get his email. I guarantee that if you aren't receiving it there are others who aren't either. Ted Hatfield

If he can do this then that should solve your problem. However, if he does this it will affect the amount of spam you receive. DNSBL checks aren't perfect but they do block a lot of spam attempts.

One of my clients uses mail provider whose IP addresses are almost all time on some blacklist and therefore I can't receive emails from him. So my question is: Is it possible to still use DNS blacklists and add domain of my client to whitelist? Will it work? From info what I've read I'm not sure... Or do DNS blacklists have higher priority and whitelist will not help me in my case? Thank you for help, Mario -- View this message in context: http://spamassassin.1065346.n5.nabble.com/Whitelist-and-DNS-blacklists-in-SpamAssassin-tp103262.html Sent from the SpamAssassin - Users mailing list archive at Nabble.com. Normally the answer would be no. This depends on how your mail provider is using the dns blacklists. For instance my mail provider queries several blacklists and will block connections from ip's on those lists well before spamassassin is called to parse the message. The only effect changing your whitelist/blacklist settings would have is if the blacklist queries occur inside of spamassassin. Your client would be well served to find a new email provider that doesn't have so many issues being on ip based blacklists. Ted Hatfield
