[exim] Debian uucp

Hi all

Yesterday someone sent an email to uucp@??? (my domain), and now Im seeing this

2006-02-08 07:32:34 1F6SuX-0002gj-Ph == uucp@??? R=userforward defer (-1): failed
to stat /var/spool/uucp/. (No such file or directory)

Did a check on my /etc/passwd file

mail:~# cat /etc/passwd | grep -i uucp
uucp:x:10:10:uucp:/var/spool/uucp:/bin/sh
mail:~#

So my question is, for the Debian distobution, would it be safe to delete this user, or would anyone
have another solution to this problem.

I know its not doing anything, but I dont like seeing this type of attempts / activity in my logs.

Kind Regards
Brent Clark
