Spam + Attachment filtering now implemented
Sent 3/3/2004

Greetings, customers on the Summit Internet Services – Email/Web Services please see updated info below on both our on-going Spam filtering and our new Attachment Filtering!
Spam Update
————————
As you are aware, we implemented “Spam” filtering on the server in the middle of last year and while some spam still get’s through the amount being blocked is really impressive. For example: as of midnight last night or statistics show that for the preceding fourteen days (looking at just Monday – Friday traffic) the mail server handled 53,566 pieces of email. Of that, the Server identified 12,994 pieces as probable “spam” and quarantined those messages. We are still doing cursory reviews of ALL mail that is caught and redirecting them to you. However, while 70 such messages were
redirecting as part of the review only 12 of those messages were actually redirected due to the person that sent the original message requesting that the review be conducted per the instructions that were bounced back to them when their message was originally caught. Still, this demonstrates that we are only having a 0.54% “false-positive” for valid email that are being trapped by the filters.
Attachment Filtering
———————–
In response to the incredible amount of worm/virus traffic flowing across the ‘Net we have implemented, as of this morning, some “rules” on the server that hopefully will cut down on this “type” of nuisance. Any message that contains a file attachment (either in the body or the header of the message) that ends in the following extension types will be quarantined and be subject to deletion by our system on a weekly basis.
Attachment types not allowed through the system:
..SCR, .PIF, .REG, .BAT, .VBS, .SHS, .EXE
If you have any questions about either of these features please feel free to email back with questions or comments.
