I do not recommend the use of sender_canonical_maps, the problem
with this is that there is no good way to distiguish between sender
headers and recipient headers. A sender may include himself in a
"Cc:" header, which should be rewritten just like the "From:"
header, but is not with "sender_canonical_maps".
Instead, one would typically rewrite all headers and the envelope
sender, leaving only the envelope recipients unmodified if those
should be left alone.
canonical_maps = ...
canonical_classes = envelope_sender, header_sender, header_recipient
Much of course depends on what you're trying to achieve with
"sender-only" rewriting. Good luck.
