    Oleg> Content-Encoding: gzip

Thanks.  I'm not having much success with it, though generating messages
seems to work ok.  Maybe I can't For example, Thunderbird insists on
displaying the raw gzipped data (not the base64-encoded version which is in
the attachment) and doesn't gunzip such attachments when I try to save them.

Is it only supposed to undo the content-transfer-encoding?

Here's the start of one of my attachments:

    Content-Type: text/csv; charset="us-ascii"
    MIME-Version: 1.0
    Content-Encoding: gzip
    Content-Transfer-Encoding: base64
    Content-Disposition: attachment; filename="somefile.csv"
