Odd. I've been blocking a few hundred of these a day and haven't seen a + in
a TZ yet. I ran the ACL with exiscan blocking files with a .zip extension
combined for several hours and none slipped past the DATA ACL to be blocked
by exiscan. Oh well. Perhaps a server in the middle is rewriting the invalid
Date: header or something.

And FWIW you need to block more than just that one file name. There are 5 or
6 I believe. Check your favorite AV site for details.

In any case this DATA ACL seems to have no false positives. It's caught a
few other infected messages as well (with .pif and .exe attachments --
perhaps a previous variation of Sobig)
