a list I use. (It's not totally public). It catches a LOT of the junk from bad-looking rDNS. I'll ask if I can reveal details.

Thanks, Larry Rosenman (Sorry for taking THIS lists bandwidth, but I know Marc is on it, and I can't email him Directly because of this). Well, the reverse lookup is 5.ctyme.com - I suppose I could change that but why do you think it's dynamic? Dynamic/Generic (I.E. it looks like just a generic place holder). So would five.ctyme.com also trigger your filter, Larry (assuming that both A and PTR were changed)? There isn't exactly a huge difference between the names 5.cytime.com and five.cytime.com. 1) the pattern *WAS* [0-9]+.ctyme.com 2) it's been removed. That's interesting - where did this pattern [0-9]+.ctyme.com come from originally? -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
