bypassing SpamAssassin and virus checks for ...

[Robert Lopez]

This college has contracted with an organization to handle
all emergency communications which will be sent by text
message to those who sign up and by email to everyone.
That organization has requested certain "whitelisting" to
occur on our email gateways.

I have done the whitelisting I can do on Postfix.
If I had a better understanding of Postfix, it might have
been better to have Postfix bypass MailScanner.

Now I need to tell MailScanner to allow the email to
bypass SpamAssassin and the virus checking software.

Thus far I have not utilized any RuleSets files.
The book says bypassing SpamAssassin does not
bypass the virus checking.

As I plan I am looking at these two modifications:

--------------------------------------------------------------------------------

1) Add to
/etc/MailScanner/rules/spam.whitelist.rules
and enable use in /etc/MailScanner/MailScanner.conf

From:		207.66.21.3		yes
From:		69.25.199.33		yes
From:		205.237.106.3		yes
From:		@getrave.com		yes
From:		@ravewireless.com	yes
From:		@ravemobilesafety.com	yes
From:		*cnm.edu at getrave.com	yes
From:		No-reply at getrave.com	yes

--------------------------------------------------------------------------------

2) Add to
/etc/MailScanner/rules/virus.scanning.rules
and enable use in /etc/MailScanner/MailScanner.conf

From:		207.66.21.3		yes
From:		69.25.199.33		yes
From:		205.237.106.3		yes
From:		@getrave.com		yes
From:		@ravewireless.com	yes
From:		@ravemobilesafety.com	yes
From:		*cnm.edu at getrave.com	yes
From:		No-reply at getrave.com	yes

--------------------------------------------------------------------------------

The two sets of lines are exactly the same in both of the files.
It seems redundant. Because in a real emergency the
service will "open multiple SMTP connections and attempt to
send a large number of emails in a short period of time" I
should be concerned with system load.

Are my plans sufficient?
Is there something more efficient I should consider?
