OK, added a remark that socks provides no interfaces for run-time
configuration that fetchmail could use.

OK

Well, the issue at hand was that qmail-inject was not being given the
recipient as command-line options, but instead had to rely on parsing
the headers. This kind of abuse can happen with the sendmail interface
too. I've revised the whole --mda action based on your patch and made
the distinction between missing the %T and qmail-inject's nonstandard
interfaces clearer.

Looks we already have this for recent 6.3.X releases.

Perhaps we could make the "no 6.2.X support" policy even stricter (and
not let users get away with "I know I have to update") for this list to
avoid discussing fixed issues like this one :-)

fetchmail.c (SVN version on branches/BRANCH_6-3):

            /*
             * can't handle multidrop mailboxes without "envelope"
             * option, this causes truckloads full of support complaints
             * "all mail forwarded to postmaster"
             */
            if (MULTIDROP(ctl) && !ctl->server.envelope)
            {
                report(stderr, GT_("warning: multidrop for %s requires
envelope option!\n"), ctl->server.pollname);
                report(stderr, GT_("warning: Do not ask for support if
all mail goes to postmaster!\n"));
            }

Will consider, it's on the 6.4 TODO.txt.

THank you!
