just discussed recently on the zmailer list.
basically 2 ways:
1) Matti indicates that the following in smtpserver.conf
should work for the % redirect:
or 2) add the following to cf/rrouter.conf at the beginning
of the rrouter function:
tsift "$origaddr" in
# "percent redirect"
return (((error percent-redirect "$origaddr" $A))) ;;
# "colon pathing"
return (((error colon-pathing "$origaddr" $A))) ;;
Also you may want to ensure that the testers do not allow
MAIL FROM: <sender@[x.x.x.x]>
(where x.x.x. is your smtpserver host IP designation)
