Of course there are spambots which play around greylisting, but they aren't yet that widely used. > On top of that, I guess you have whitelisted large mail providers like > gmail who try to send a single mail from several IP's, thus hitting your > greylist over and over again, and then just giving up? :) some greylisting packages have their whitelists already pre-filled in the distribution package, so it works quite well (we used http://policyd.sourceforge.net/ , and I have no complaints about this software, and neither do the users.

Re: [swinog] RBL's (again) (Was: Anyone from Green here?)
by Stanislav Sinyagin 20 Oct '08

actually greylisting works pretty well, and the whitelist of exceptions is relatively small (not more than 300 entries as far as I remember). Also if you communicate the value of it to the customers, they tend to agree that having 90% of spam filtered before entering the system is worth waiting for half an hour for email from a new source. It's also a matter of resources: if you don't want or cannot enable greylisting, you have to invest more resources into a more sophisticated mail filtering software. Even if it's available for free, still developing and maintaining your solution might become too expensive. so, basically as we discussed it already last week in regards to Skype: use the right tools for the right task :-) ----- Original Message ---- > From: Tonnerre Lombard <tonnerre(a)bsdprojects.net> > To: swinog(a)swinog.ch > Cc: swinog(a)lists.swinog.ch; per.jessen(a)enidan.ch > Sent: Friday, October 17, 2008 5:27:10 PM > Subject: Re: [swinog] RBL's (again) (Was: Anyone from Green here?) > > Salut, Per, > > On Fri, 17 Oct 2008 12:47:48 +0200, Per Jessen wrote: > > Another option is to disable greylisting just for that one > > mailserver. > > This implies that either you know all servers hosting broken scripts > (NP-complete I think) or your customers will always communicate > problems.
