Looks like a bug to me; I think that failedrecips line should
be failedrecips.extend([chunk]) for Python 1.5.2 anyway.

But it's probably a latent bug because Sendmail shouldn't be failing
to get you into that code.  It'd be worth fixing that line (as above)
and switching back to Sendmail.py to see what's going wrong to cause
sendmail failures.

I'll file the bug.
