Replacing email envelope

[jon.sp2@wp.pl]

Hi,   Could you please advice how I can replace envelope of a message received on my server? Best would be using sieve.   Simple case - email   A at example.com  receives message, which I'd like to repack into new envelope (I want to have control what values in the envelope will be there - from, to, replay-to et.c) and send to   B at test.com .   At first I wanted to use editheader extension, but it is not allowing me to modify From or To values as far as I can tell. Another idea was to use envelope, but I don't see any way of editing values. Only reading.   Now, I am thinking of writing script and from sieve it will be passed there, where I'll do message parsing and send new message using mutt or something similar. Frankly speaking I suppose there is much better solution to that and I'd appreciate any advice on the topic.   Thanks,  Jon
