When pMX is back online sMX fwds it's queue, but at that point pMX rejects to sMX...who then rejects to Sender. Short of having a complete list of all your valid recipients on the secondary MX, or having some way for them to obtain this information, I don't think you can. Also note that you have to completely replicate the full anti-spam/anti-virus configuration from the primary MXes to the secondary MXes, for the same reasons.I'm not sure how I can get away from that happening. -- Brad Knowles, <[email protected]> "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety." -- Benjamin Franklin (1706-1790), reply of the Pennsylvania Assembly to the Governor, November 11, 1755 SAGE member since 1995.
