Some people do. I only use it for backup mx systems, as the reports of problems in primary mx systems has been too high for what my customers will put up with.
Hi,
Never Mind, I see I did send it.
As to Maciej question, yes quite a few people use the greylist patch. We do with about 200 domains, and my personal spam has dropped from 200 a day to 4 or 5 a week.
There are problems with
1 - Old NT exchange servers (some banks still use them), you need to white list them, no fix except to get them to upgrade (good luck).
2 - Mail Max, apparently a mail server for Windows, not sure if there is a fix yet, we've whitelisted where we need too.
3 - Old Novell groupwise servers, again we white list where needed.
All of them bounce emails when giving a 421 soft error instead of retrying. The majority of our clients and myself can live with that, we've only had one exception in 200 domains, and we just allow all email through for that domain.
I'm in the process of re-writing the greylist patch to allow per user whitelisting (local users) as well as adding that option to my php SA user interface. After that it will be up to the user if they want to use greylisting or not.
Regards.
Rick
