Two observations:

1) fetchmail is buggy and in a way that can cause it to leave main
sitting in your mailbox at the ISP. I gave up on it several years back
and replaced it with getmail, which doesn't have these problems. If you
use one, you can even use the same MDA you wrote for fetchmail with
getmail.
 
2) With that setup you can punt almost anything out the door and know
that it will come back via your ISP and fetchmail/getmail. Simply point
a mail client at your ISP's MTA and send mail to yourself with it: the
message will go through the ISP's delivery mechanism and back to your
local MTA via fetchmail/getmail. You can even forge a GMAIL From: line
unless, of course, your ISP has rules that would prevent that, but you
can check for that easily enough: send a test message with your usual
sender address: it should come back. Try another with a forged GMAIL
sender: if you don't see it come back you know that your ISP has a
forged sender trap installed.
