Postgrey anyone?

Question

Hi Guys, just quick question on if anyone is using postgrey in conjuction with Puremessage. Not sure if this would make puremessage more effective. We are on 5.5.6 and still seeing a lot of spam. Yes I know we are advised to upgrade to 5.6.0 but we don't see the need since the spam engine has not been upgraded. And yes we are aware that this would not be supported by Sophos.

Thanks

Hi mrdky, I'm not using this, and after reading the white paper on greylisting, I doubt I ever would. I have time-based constraints that I have to mangae and delaying a message by defult for 60 min isn't an option. Having said that, it does seem like an interesting way to help deal with some spam. I use the IP Block list from Sophos and this seems to cut down on the vast majority of junk for us. The rest of it is handled by the rules or custom black-lists. Still, I wonder if it's something Sophos might consider adding into PureMessage? Erric :5401
