I had a similar experience with github trying to send a mail with different IP each time when spamd grey-trapped the first attempt. bgp-spamd whitelisted IPs had all the IPs with which github was trying to send mail. -- You received this mail because you are subscribed to misc@opensmtpd.org To unsubscribe, send a mail to: misc+unsubscr...@opensmtpd.org

I only use greylisting and fopr big hosts like gmail and yahoo, I have a script that queries their SPF records to whitelist the MX servers that they advertise. I tried to do this, but there were just too many to keep track of, and I noticed that a fair amount of the hosts connecting weren't even in the SPF. Greylisting became less and less helpful, unfortunately. I've been running blacklist-only for a few years. Luckily, I don't have a busy host. -- John D.
