You get a reference to the header, so you only need to get the
header and set the fields. You do not need to put the header back
But please write to the mailing list and not to my personal mail
address. Thank you.

Sorry, the same query. How I put the certain field on the

I tried to get the original header by get header but seems no
method to put back after modified? Can I have ur suggestion?
