(the right side of the expression). For example, the following message filter rule 
evaluates to 

true

 if the sender group of the message matches the regular 

expression Internal, and, if so, sends the message to an alternate mail host. 

senderGroupFilter:

      if (sendergroup == "Internal")

      {

        alt-mailhost("[172.17.0.1]");

      }

Body size refers to the size of the message, including both headers and 
attachments. The 

body-size

 rule selects those messages where the body size 

compares as directed to a given number. For example, the following filter bounces 
any message where the body size is greater than 5 megabytes.

BigFilter:

   if (body-size > 5M)

   {

        bounce();

   }

The 

body-size

 can be compared in the following ways:

body-size < 10M

Less than

body-size <= 10M

Less than or equal

body-size > 10M

Greater than

body-size >= 10M

Greater than or equal
