And other mail systems will be rejecting your mail because the envelope 
(the source and destination information that MTAs wrap round a message in 
transit) is incorrect.

The way to correct this in Postfix is to do a canonical rewrite.  You 
want to get Postfix to rewrite both the envelope and message headers to 
match what you have in your From: header.

To do this, create a file called (e.g.) /etc/postfix/rewrite.  Add to it 
a line like

jon at hal.chagny  jon at jons.official.address

Then add this line to main.cf

sender_canonical_maps = hash:/etc/postfix/rewrite

and run

postmap /etc/postfix/rewrite;postfix reload

That should do it.  Have a look at the canonical manpage and the 
sample-canonical.cf file in the Postfix documentation.
