I'd say it is SA's fault, the helo is: 66-220-155-138.mail-mail.facebook.com which is clearly not a dynamic address because of the .mail-mail. label. __HELO_DYNAMIC_IPADDR2 has an exception for [-.]static[-.], but nothing else. By contrast the default for the Botnet plugin is/was: botnet_serverwords e?mail(out)? mta mx(pool)? relay smtp botnet_serverwords static

Here's the two that put it over: 3.9 HELO_DYNAMIC_IPADDR2 Relay HELO'd using suspicious hostname (IP addr 2) 1.5 RCVD_IN_SORBS_WEB RBL: SORBS: sender is an abusable web server [66.220.155.138 listed in dnsbl.sorbs.net] Here's the offending header: Received: from 66-220-155-138.mail-mail.facebook.com (66-220-155-138.mail-mail.facebook.com [66.220.155.138]) So who do I bitch at? I've never found any good way to complain to Facebook. I long ago sighed and globally whitelisted as many generic Facebook sending channels as I could find because of lunacy like this. whitelist_from_rcvd *@facebookmail.com .tfbnw.com whitelist_from_rcvd *@facebookmail.com .facebook.com whitelist_from_rcvd *@facebookappmail.com .tfbnw.com whitelist_from_rcvd *@facebookappmail.com .facebook.com whitelist_from_dkim *@facebookmail.com whitelist_from_dkim *@mail.instagram.com So tempting to let my inner BOFH out and just convert those to blacklist_from entries instead though... Of course, having whitelisted them we now have a couple of customers who routinely report various Facebook email notices as spam. -kgd

I noticed the same thing this morning. This is new for me as of yesterday. They appear legit, but they get caught up in my filters for the dyn ip "appearance".
