See http://home.pages.de/~mandree/mail/multidrop to see which multidrop
scenarios work reliably and which don't.

Many MTAS omit the recipient from Received: headers when there is more
than one as is the case in Bcc setups, although that does not appear to
be the problem here (but it might if you wrote to two different Bcc:
recipients of your own domain)

fetchmail expects a "by some.host.name for <so...@ex...>" format,
and also performs some checking on some.host.name - if that doesn't fit,
it doesn't accept the address.

So it likes this header better because it has the "by mycompany.com"
before "for <te...@my...>" - but doesn't accept the "by"
part.  You might trick fetchmail into believing that by adding

aka mycompany.com

to your configuration (before the "user" keyword). I don't know if that
works though -- no guarantees.

I suggest:

1. check if there is a better header. If not, try to arrange for one,
   such as X-Original-To, Envelope-To, Delivered-To. See the URL above,
   and feel free to quote the URL to your ISP. If you have got a better
   header, adjust the Envelope option accordingly.

2. do not run fetchmail as root - that's a basic safety measure to limit
   impact should a bug I have overseen be discovered. Since you are
   forwarding via SMTP, fetchmail does not need root privileges.

   Create a "fetchmail" user, copy /etc/fetchmailrc
   to ~fetchmail/.fetchmailrc and use this command to start fetchmail
   under the fetchmail user account:

   su fetchmail -c "fetchmail"
