Re: [mailop] Meta outgoing servers in black list (SORBS, 0SPAM...)
It would be helpful if Meta used a better PTR naming convention for these servers.. ;) host 66.220.155.136 136.155.220.66.in-addr.arpa domain name pointer 66-220-155-136.mail-mail.facebook.com. Not sure who dreamed up that one..

One (possibly naive) option is to extract from SPF the outbound MXes for domains you want to receive mail from, such as what I describe in https://www.nxdomain.no/~peter/goodness_enumerated_by_robots.html (or if you prefer nicer formatting at the cost of *all* the trackers G has for you https://bsdly.blogspot.com/2018/11/goodness-enumerated-by-robots-or.html) - Peter -- Peter N.

[mailop] Meta outgoing servers in black list (SORBS, 0SPAM...)
Hi, I've got a customer complaining that they don't receive emails from Meta for password reset. We have tracked down this to see that a lot of this servers are blacklisted in popular blacklists. A small subset of blacklisted addresses are: 66.220.155.136 66.220.155.140 66.220.155.142 66.220.155.143 66.220.155.145 66.220.155.147 66.220.155.148 66.220.155.151 66.220.155.152 66.220.155.153 66.220.155.155 66.220.155.156 66.220.155.157 66.220.155.158 69.171.232.129 69.171.232.131 69.171.232.132 69.171.232.134 69.171.232.135 69.171.232.136 69.171.232.137 Is anyone from Meta reading this? I usually don't care when the sender is blacklisted, as our policy is that the sender has to deal with their own problems, but this particular customer has a point. Btw, how do you deal with this big players' blacklist problems? Best regards___ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
