Now see, I run a spam filter (run on CentOS, by the way *smiles*) and I have several friends' domain emails running through it. It has a pretty good filter rate, too for being all open source. -----Original Message----- From: centos-bounces@xxxxxxxxxx [mailto:centos-bounces@xxxxxxxxxx] On Behalf Of m.roth@xxxxxxxxx Sent: Thursday, August 27, 2015 9:30 AM To: CentOS mailing list <centos@xxxxxxxxxx> Subject: Re: please block user Gary Stainburn wrote: > Bad news Guys, they've just moved the emails to somewhere else and > have started again: <snip> A suggestion: there should be a way to filter using *domain* AND mailhost; that is, if emails come from a domain, and through one mailhost, then block the domain. If many domains, and the same mailhost, only then block the mailhost. I've been thinking about this since yesterday, when I got back from vacation, to hear from my manager that he had to screw with mailman, because we were getting a lot of emails from elsewhere, subscribing to one or more of our lists... and having the target be one of three gmail accounts - a DDoS against them (and we assume that they're doing it to a lot of other places). Anyway, given the number of times I've been blocked by nixspam (which I found is run by IX, a German IT mag, and that they don't answer emails to *them*, either), I've been trying to think of a *reasonable* way to block that doesn't do collective punishment to the many domains of a huge hosting provider, and that's my best thought so far. mark _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
