There is an exception to the above if in General Settings the following options are
set. The attachments will be deleted if they match the setting:
Using Forefront to Guard Microsoft Exchange Server ??? Chapter 5 207
?– Delete Corrupted Compressed Files
?– Delete Corrupted Uuencoded Files
?– Delete Encrypted Compressed Files
The fi nal two options are to Send Notifi cations and to Quarantine Files. The Send
Notifi cations option allows for notifi cation e-mails to be sent if a virus is detected. These
e-mails are confi gurable and will be covered later in this section. The Quarantine Files
option allows you to specify if attachments are quarantined when a virus is detected; this
will occur no matter what you set the Action to be.
Scanner Updates
The Scanner Updates section allows you to confi gure the update source for the AV
engines and how often they are updated. By default, all of the engines are updated
on an hourly basis at 5-minute intervals of each other; this includes engines that are
currently not being used.
For each of the engines, you can specify a primary and secondary update location.
This can either be left at the default (which is the Microsoft Update Web site)
or can be changed to point to an internal distribution server. Any FSE server can be
set to be a redistribution server (covered later in this section). Alternatively, FSSMC
can be used to distribute updates.
The choice of where to download updates from depends on your requirements.
