using INTERNALDATE instead, in this special-case workaround, would
mean that messages don't show up with a zero date - and yes, it would
help a lot. these are messages that are arriving via SMTP, so
INTERNALDATE would represent the date that the message was delivered
to the destination mailbox.

I completely agree it would be better to fix the MUA, but what's out
there right now is broken, and a workaround for a broken client is
better than no workaround at all.

I don't know, I haven't checked yet. but that won't magically fix
existing clients that are in widespread use.

grant.
