The spam filtering/mail security system we use for 70 school districts in
Western NY blocks attachments with extensions that Microsot has deemed to
be unsafe (See http://support.microsoft.com/kb/291369/en-us ), which
includes the extension .URL.. A teacher got dropped form a State Ed
listserv becuase we rejected (554 5.7.1 Attachments with file extension
url are not accepted Message rejected by spam filter) the message at the
SMTP level.
Is there any advice I can pass on to the list owner on how to block that,
and other unsafe extensions, to prevent future problems and make the list
safer for all their subscribers?
