[wplug-bsd] Periodic -- phantom email

[Brandon Kuczenski]

About a month ago I added a new script to my /etc/periodic/security 
directory.  The script looks through the security log for notations 
regarding people updating their IMAP passwords, and it's nothing special. 
It works fine.

The day after I installed it, I began to get these mysterious emails at 
4:42 AM (exactly when my periodic daily functions run).  The emails are 
>From root and not to anybody, so the mail daemon rejects them saying "no 
recipients specified".  There is no content to the emails, either, just 
mail from root to........... ?

The only clue I have is that I get the email every day at 4:42 AM without 
fail.  The periodic scripts take several minutes to run, and I don't get 
those outputs until 4:45 or 4:46, but the phantom email always comes right 
at 4:42 (or possibly 4:42:01)

Any ideas how I could troubleshoot this?  I already tried removing the 
script that I added that day, but I still got the email last night/this 
morning.

Thanks in Advance,
Brandon
