from : web123 at gmail.com
to : jacka at mail.com

vocation sent back
from : jacka at mail.com
to : srs0=hmc8=v7=gmail.com=web123 at mail.com



postsrsd changing return-path from web123 at gmail.com to srs0=hmc8=v7=
gmail.com=web123 at mail.com

this is no problem for me but  sieve:

Vacation's messages are always addressed to the Return-Path address

it is possible some how change this ugly to header to normal?
