Sorry, I tried the procmailrc you posted without changes running under
pre7 on my system and it behaved as expected:
procmail: No match on "^From:.*sun1.wwb.noaa.gov"
procmail: Locking "/home/roderick/Mail/spool/mbox.spool.lock"
procmail: Assigning "LASTFOLDER=/home/roderick/Mail/spool/mbox.spool"
procmail: Opening "/home/roderick/Mail/spool/mbox.spool"
procmail: Acquiring kernel-lock
procmail: Unlocking "/home/roderick/Mail/spool/mbox.spool.lock"
Subject: subject
Folder: /home/roderick/Mail/spool/mbox.spool [size]
I don't know what the problem is. If I were you my next step would be
to compile procmail with debugging and step through the relevant code.
