I also got an issue with Trend Micro blacklisting one IP (with matching DNS,RDNS,HELO) of one of my customers a few days ago. I am working for a large "international" ISP and they asked us to provide information for _ALL_ our ranges to remove this particular IP from their blacklist. Also, the mail with this info should be sent from a postmaster account. This kind of thing is almost impossible as there are many groups managing those IPs and those groups are everywhere in the world, and people (if any) being able to send a mail from postmaster@ are not doing any network related job. I told them it was impossible to give the whole info, but we could give it partially and not from a postmaster address and they disagreed. > > We should really consider some global actions against this practice, > including > not using their services. In fact nobody has any interest in using their blacklist as there are way too many false positives and they don't want to update them. So everyone using those lists is losing legitimate mails. You know how accurate blacklists are when there is a possibility to remove falsely listed IPs easily. If there is a matching static non generic DNS,RDNS and HELO, how could they possibly refuse to unlist the IP? That's about like "we know that this IP is listed by error, but we will keep this error in our lists". Just avoid Trend Micro blacklists, that's all. -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
