Re: [SURBL-Discuss] cheetahmail / rhsbl.ahbl.org

I would like to make up my mind

• whether to whitelist cheetah.com mailservers from being blocked on MTA level in order to avoid FPs when using ahbl
• whether to use rhsbl.ahbl.org to reject mails at the MTA level.

As ESPs go, CheetahMail is better than many. I'd say they're not whitehat, but light grey. I certainly would expect that email from them is usually not spam.

The AHBL lists are aggressive. If a bulk email sender isn't completely COI, that sender is likely to get listed by them. I use the AHBL on my local systems as part of SpamBouncer scoring, but I'd never reject email at the MTA level based on an AHBL blocklist hit. There is just too great a chance of a false positive.
