Hi All, This may be a Postfix issue rather than a Mailman one, but the Mailman post log (snip below) is showing some relevant info, so here goes.
This morning there was a legitimate post to a list from a subscriber with a Gmail account. Shortly after, there was a deluge of bogus posts (one every minute) repeating the same email to the list purporting to come from the same address. The Mailman "post" logs below show the original at 13:43 with the google.com ID, and the following bogus messages all with a yahoo.com ID This appears to be happening to only the one list on the server. If anyone could shed some light on this, or point me in the right direction, it'd be much appreciated.
