I've tried it out and it seems running fine. But for our situation I need something that is able to verify trough an external application and on the recipients pop3-server in realtime if the mailbox is valid. So we've tested Xwall and it seems running fine with more then 100k Messages/day.
At the same time I've switched to Declude v3 and a I can see it has reduced significantly CPU-usage even if now with Xwall each message accepted by Xwall is processed a second time by Imail/Declude. The problem is that MDLP at the moment is not able to parse the new Declude v3 logformat and so my hourly reports does not work since the reconfiguration. With Xwall it would also be possible to block all messages comming from a host IP without PTR-record. Anyone beside AOL & Co. has already enabled such a test? Looking to the results of MDLP from last month I can see that 77% of all incomming messages has valid REVDNS records. From the other 23% 20% seems to be clearly spam and most of the other 3% are in a grey zone who it's hard to say if it's legit or not. I fear if I enable Envelope blocking for sending IP's without REVDNS record this will block some legit messages send from non-mailservers (web-forms, admin. status messages, ...)
