Email Security Changes

Currently, downloading executable files from the Internet is blocked and requires that I turn off a filter in order for anyone to download such files.  This has greatly improved overall security of the network since this was implemented last year.  However, executable files or infected image files can be sent via email by someone or received in a spam message packaged as a malware file directly to your mailbox.

I have made the following changes to email security.  Executable files and images are now blocked from going directly to your mailbox. Instead they will go directly to your Postini Message Center Spam folder.  If you are expecting to receive an image from someone or an executable file, you will need to log in to your Postini Message Center to have it delivered to your mailbox.  You just go to login.postini.com and log in with your email address and password.  Look in your spam messages for the one with the file and click the deliver link next to the message.  The email and attachment will then be delivered to your mailbox for downloading.

I have also increased the file size of attachments that you can receive from 25Megs to 75Megs.  This should help when receiving large files such as PowerPoint files or large images.
