Hi, all.

I want to use grey list in mail server, currently, i use postgrey to implement it.

Any other recommended software?

perhaps you should consider asking on a MTA specific list ?

Karanbir,

I belong to several lists regarding mail. That world is pretty darned complex and many times spread first between windows and 'nix servers and then divides out into the various 'nix flavors and the few winders options.

It would REALLY be sweet if there was a list specific to CentOS and email, where all things remotely related could be discussed. Basic system discussion through to anti-spam techniques.

As a side, I could see blossoming a Wiki area specific to email which might eventually fill out to an extremely robust set of how to's for installations of what amounts to being some of the very hardest things that I've accomplished with CentOS. Yes SpamAssassin is a powerful tool, but for instance the default setup that comes out of the box is fairly weak. A trip to the SpamAssassin site will just leave you mostly confused and reading for hours only to find out that what you think is good might not be applicable to your system.

Googling doesn't help much either. It's just about impossible to get a decent return on a search as there is just too much information and the relevance goes down to all but useless.

I think a fair number of the members of this list and the users of CentOS are using it in a server environment and require email. And basically, if you require email that is not exclusively internal to a network, spam is a huge battle which requires constant time... and I mean hours and hours and hours and hours of time. I just spent about 4 days on this again this past week.

Do you or anyone else have a good idea for how something like this might be accomplished? If CentOS can't handle what might be a pretty good additional mail volume or storage/traffic volume, would anyone else perhaps step up the the plate? If so, would CentOS readily advertise this list on the site so that it would gain enough users to be a valuable service?

I would offer to do it here, but I fear I don't have enough bandwidth as I think a list like this would be a huge success, if people knew it existed.

Best Regards, John Hinton

I know how that feels :D

Given that, I think it might be a good idea to tackle some of this on the wiki itself rather than needing a list for it. One thing that we are working on at the moment is to try and get a commenting system working on the wiki - so if drive-by users have comments / issues / feedback or even a contribution of some sort in content - they can drop that in there with a near zero barrier to entry. The Editorial Team on the wiki can then evaluate that for inclusion in the main article or leave it as a comment.

I am about to take the plunge into this area after about 2 years and completely rework my own anti-spam system. Hope to take loads of notes and get them onto the wiki.

We have plenty of resources within the CentOS setup. I dont see hosting something of this nature being too hard. However, i think it might be important to work out what we want to host. IMHO, email is too niche an area to have a dedicated list for it. Something like NetworkServices might be a better target.

I use ASSP - http://assp.sourceforge.net/ with a Wiki at http://www.asspsmtp.org

It does more than greylisting too.

looks interesting, would you consider writing an article on wiki.centos.org on how one might integrate that into a centos distro included MTA ?
