I see many of these on several Linux/Sendmail/Cyrus IMAP server. As far as I could determine, they are actual deliveries of completely empty mails. Perhaps some malfunctioning spammer tool or worm, as they do tend to crop up mainly on accounts who also get a lot of maltraffic. -- Tilman Schmidt [EMAIL PROTECTED] Phoenix Software GmbH Tel. +49 228 97199 0 Adolf-Hombitzer-Str. 12 Fax +49 228 97199 99 53227 Bonn, Germany http://www.phoenixsoftware.de ------------------------------------------------------- This SF.Net email sponsored by Black Hat Briefings & Training.
