This was done as soon as I was made aware of the SRS stuff for Postfix and to date seems to have ‘fixed’ the issue for us. I am still of the opinion that SPF is broken but seem to be fairly alone holding that opinion. I suppose if I had encountered issues with relaying earlier I might have become aware of SRS sooner but as I hadn’t I didn’t. Old story that one doesn’t know what one doesn’t know. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Glen Eustace, GodZone Internet Services, a division of AGRE Enterprises Ltd., P.O.
