Create one of those shitmail accounts and send your server some 'test' messages. Eventually they'll validate through greylisting. Once low volume regular mails come through, it ceases to be a problem. -- You received this mail because you are subscribed to misc@opensmtpd.org To unsubscribe, send a mail to: misc+unsubscr...@opensmtpd.org

Infected PCs in the sales office, employee WiFi zones, tape silos, routers, web servers, etc... are not valid mail exchangers, so SPF records of 'valid sending IP address' can't be trusted. SPF might be slightly helpful, but it is not reliable. -- You received this mail because you are subscribed to misc@opensmtpd.org To unsubscribe, send a mail to: misc+unsubscr...@opensmtpd.org

SPF is grossly abused, and DKIM mail must be received before it can be inspected. Useless. See the section "SPF found potentially useful" and the 1st comment of: http://bsdly.blogspot.co.uk/2007/07/harvesting-noise-while-its-still-fresh.html OpenBSD's spamd + greyscanner rocks! These helpers work with spamd for bulk trap address loading: http://web.britvault.co.uk/products/abersnuik/ http://web.britvault.co.uk/products/spamdba/ I've vastly modified greyscanner to check DNS PTR records & DNS RBLs. e.g: https://bitbucket.org/bonetruck/greyscanner/pull-request/5/ Nothing else is needed to filter incoming spam. -- You received this mail because you are subscribed to misc@opensmtpd.org To unsubscribe, send a mail to: misc+unsubscr...@opensmtpd.org
