imaplib & Received: header(s)???

[Petri Savolainen]

Hello,

Is there a way to get at the "Received" header(s) or is there something 
in imaplib or imap server implementations that hides these? If not, what 
IMAP FETCH command should be used? I've used for example 
"BODY[HEADER.FIELDS (RECEIVED)]" and it always returns empty ("\r\n"). 
Despite the Received - header existing, as demonstrated by taking a look 
at message sources via desktop email clients.

I need to get at the Received-for header to figure out at which address 
we received an email. We subscribe to a number of mailing lists using 
per-mailing-list addresses, and often, To: field contains something else 
than our address, thus the need for Received-for.

Any help would be much appreciated - this is baffling me and I've not 
found anything recent that would help.

Thanks,

  Petri
