mailscann and japanese filename on attachement

[Aram Yegenian]

as the error message states, MailScanner is blocking
long filenames in case they're an attack against ms
outlook.

what you can do is edit the file 
/etc/MailScanner/filename.rules.conf and comment out
the line that begins with:
"deny    .{150,}                 Very long filename,
possible OE attack..."

just be careful because this will make ms outlook
express users susceptible to that kind of attack. 

i did comment it out at my installation, but most of
the users use either thunderbird or apple mail, and
only a few use ms outlook (note that the warning says
outlook express)

regards,
aram yegenian
