Verify RFC822-compliant Date: line??

Verify RFC822-compliant Date: line??

[swa]

Hi,

my SPAM catcher barks at the following `Date' line. Anything wrong with
that?

Here's the procmail recipe which is supposed to nuke mail with an invalid date.

# Verify RFC822-compliant Date: line
:0
* ! ^X-Mailer: Windows Eudora Light Version 3.0.1 (16)
* ! ^Date:[	]+((Sun|Mon|Tue|Wed|Thu|Fri|Sat),[	]+)?\
    [0-3]?[0-9][	]+\
    (Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec)[	]+\
    ((19)?[789][0-9]|(20)?[01][0-9])[	]+\
    (0?[0-9]|1[0-9]|2[0-3]):[0-5][0-9](:[0-5][0-9])?[	]+\
    ([+-][0-1][0-9][03]0|"?\(?(UT|GMT|EST|EDT|CST|CDT|MST|MDT|PST|PDT|[A-I]|[K-Z])\)?"?)
{ JFMATCH="$JFSEC: Noncompliant Date line" INCLUDERC=$JFDIR/junkfilter.match }

Thanks,
Stefan.

Yes, the Date is invalid.  There is no such time zone as "+-500".

This should be fixed in Pterodactyl Gnus 0.24.

Perhaps I should put the weekday in there as well.

The last time I suggested this it sparked a rather rancid flame war¹
