Hi all, New user to spamd, love it.
In getting our low traffic email server running, the first thing I noticed while following the logs that sites like gmail et al will retry a message from a different host. Sometimes gmail will send once, try again very soon again from the same host and then queue it, but the queued email might be sent by a different server. I understand that spamd is tracking messages based on sender, receiver and IP address, and then this can cause the problem. Has anyone looked at using the message ID in deciding to whitelist a host? ie, track the hosts by IP address, but if a previously greylisted host has sent message id 1234 and another host tries to redeliver 1234 within the passtime requirements, whitelist both? Obviously it would be an optional flag, but it seems the likely hood of some spam bot being able to guess the message id and who has just sent you a message to bypass this would be low. Open to ideas and if it is already on the cards great, if not, willing to look into the source myself. Mikel
