Well... (takes a deep breath): If a message arrives claiming to be from [email protected], and example.com has an SPF record of "-all", and you subsequently either send the message through your filters, SpamAssassin, anti-virus and perhaps even accept the message then you've completely wasted the resources you have assigned to the message. You won't actually *know* if SRS is in use - you may be able to deduce with high accuracy from the envelope FROM format, but you won't know absolutely. I suppose what I'm trying to say there is that you must ignore SRS, because usage of it on a remote server has no relevance to your server. All that above is for operators of an MX, ie. those *receiving* mail. "Ignoring" SPF and SRS on outgoing mail is left as an exercise for the reader ;-) Graeme -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
