[Fetchmail-users] Fetchmail 6.3.26-6 Corrupting Group Address Headers.

[Ralph C. <ra...@in...>]

Hi,

I used fetchmail 6.3.26-6 on Arch Linux to fetch using IMAP an email
that had a To header with two email addresses, the first a group
address.  The mailing list archive has what was sent to list members.

    $ curl -sS ftp://lists.gnu.org/nmh-workers/2017-11 |
    > sed -n '/Sat Nov 18 19:42:55 2017/,/^To:/p' |
    > sed -n '$p'
    To: nmh-announce: ;, nmh...@no... 
    $

After fetchmail had passed it to my local Postfix, it had been
corrupted.

    To: nmh-announce: ;, ""@ruis.pair.com, nmh...@no...

ruis.pair.com was the IMAP peer.

I confirmed it was fetchmail and not Postfix at fault by arranging a
test message to arrive at the peer, inspecting it by manually typing
IMAP commands to show it wasn't corrupted, and then capturing
fetchmail's verbose output on fetching it.

    About to rewrite To: group-addr: ;, ra...@ex......
    ...rewritten version is To: group-addr: ;@ruis.pair.com, ra...@ex....

Please acknowledge the bug.  (I found it hard to see where bugs should
be reported when I looked at fetchmail.info and elsewhere.)
