Re: stackexchange.com in URIBL (false positive?) *** Spam 5.7
Oh I can surely change anything I want. But I don't want to weaken my spam filter. It's weak enough already. Spam is getting more and more through. It got to the point where I have to reconsider my complete mail receiving strategy with subaddresses, filters and a set of inbox subfolders to keep anything unknown away from me and only put in my inbox what I already know. -Yves Von: Reindl Harald Gesendet: Sa, 2018-07-28 21:23 +0200 Am 28.07.2018 um 21:20 schrieb Yves Goergen: I've received a notification e-mail from stackexchange.com (stackoverflow.com) with a high spam score.

Re: stackexchange.com in URIBL (false positive?)
Yes, I have changed the value of this rule long ago. It seemed to be better. I may have to turn it down a little. And I am the admin myself but I'm no expert in spam fighting. Especially what the reason or source of that blacklisting is. I just see the rule matched and I consider that wrong because stackexchange is a service I use often and it never sent my anything unexpected. So what is the reason for this host being listed? -Yves Von: RW Gesendet: Sa, 2018-07-28 21:35 +0200 On Sat, 28 Jul 2018 21:20:49 +0200 Yves Goergen wrote: Hello, I've received a notification e-mail from stackexchange.com (stackoverflow.com) with a high spam score.

It uses the firewall (IPCop) as a caching DNS server, and the ISP's DNS as a fallback (not that that would help if the firewall were down). I'll see what I need to do to update. I think I used yum to install it in the first place, but something's hosed in the package dependencies. I'll get to work on that see if I can get a newer spamassassin installed. Thanks for your help!

Strangely though, when I go to the SURBL checker at rulesemporium.com, the site is NOT shown as being listed on any of these lists. Are you sure you are checking the right domain at the surbl website? There could be many domains checked, did you check them all? Have you tried pumping the message through the command-line SA? Bayes correctly considers these emails to NOT be spam, but the 4 URIBL positives are enough to put the score over the top. I have included this domain in the whitelist in sa-mimedefang.cf, but that doesn't help. How, exactly, did you do this? whitelist_from? whitelist_from_rcvd? Either of those, if set properly, should cause a -100 point bias to the message, clearly way beyond the reach of URIBL FPs. That suggests to me you used something else, or it's not working due using the wrong second parameter on a whitelist_from_rcvd. What might cause these lookups to return false positives? It could be a short-term listing that got pulled from SURBL shortly after being added. However, if it's persistent, that's unlikely.
