Gmail outright rejects mail from my server delivered via ipv6, but allows it via ipv4.
What this means is that I'm going to have to simply maintain a list of gmail MX AAAA's and pump them into an ipfw reset rule like:
reset tcp from me to 2a00:1450:400c:c02::/64 dst-port 25
On the same note, I am getting continually added to various google groups that send me a bunch of Indian CV's for people seeking employment. Google apparently will anyone be added to a google group without confirmation.
I keep maintaining a procmail rule that looks like this:
:0 * 1^0 ^List-ID:.*.shaikhgroups.net * 1^0 ^List-ID:.*zain-22.zaryabi.info * 1^0 ^List-ID:.*hadi-20.hadebad.info # ...more goes here | /home/danm/spamcopquick.pl
I should probably write a SpamAssassin module that detects this crap, and once it does, rather than filtering the body, detects the list-header and reports as appropriate. (I don't want to reject at SMTP transaction time, because I want the lists to get onto google's radar as a problem that's not simply a delivery issue)
Note: Looks like this journal theme doesn't show the markdown "code" properly. Dammit.
