Mailscanner, forwarding and SPF - the answer is SRS

Hi Don,

I found an answer to the SPF issue on forwarded emails - SRS.  I found the setting at Barracuda in advanced settings.  This rewrites the sender envelope info such that the next hop will accept it as it appears to be (in my case) from and GoDaddy is now happy.  (envelope-sender <srs0=by7r=2l=<my_domain>.ca=daniel at>)
Now what you need is a way to implement SRS in EFA.  Note: PostSRSd is not currently part of EFA - that's not to say it cannot be added!  See

Good luck,
