i've had a chance to look and the whatsnew.txt file says there is a limit
of 50 forward mappings like the above allowed... A32 brought that feature
to us... at some point between A32 and A38, the "[EchoImport]"
stanza's name was changed to "[ImportEchomail]" but i can't find
that in the whatsnew... in any case searching for "forward" or
"[EchoImport]" should find the desired info ;)
