Has anyone done this. I have been looking at greylisting and it seems to a simple and very effective way to cut down spam. Has anyone had any success in implementing this in an IMail environment?

I guess it would take another smtp server with the greylisting and then forward all good emails to the imail, right? The only issue I have with that is the outgoing mail. If it's the IMail box that delivers directly there would need to be an MX record of that IP address, thus allowing incoming mail messages to be delivered directly to the IMail server, being as it is the secondary MX. Unless the Imail server forwards everything through the same smtp server handling incoming connections??

Looking for some real world feedback.

we have 3 servers sitting infront of our imail server that do greylisting. i have found it to be a very good solution to cut out a lot of spam. after the emails pass through greylisting they get forwarded to the main imail server. seems to work pretty good imo.

May I ask what servers you have installed infront of your IMail?

We use Symantec Mail Security for SMTP for mail filtering.

Hello from Germany

Every day checking the smtp-log, I think to myself: "Please, please godvather of IPSWITCH/IMAIL give me Greylisting!".
But my wishes will not heared.

IMAIL is not the cashcow for Ipswitch and the wishes will be wishes.
I'm looking all so to hMailServer!

Kind regards

Rainer Noa
