The 

rcpt-to

 rule is message-based. If a message has multiple recipients, only one 

recipient has to match the rule for the specified action to affect the message to all 
recipients. 

The 

rcpt-to-group

 rule selects those messages where any Envelope Recipient is 

found to be a member of the LDAP group given. For example, the following filter 
drops all messages sent with an email address within the LDAP group 
“ExpiredAccounts.”

expiredFilter:

   if (rcpt-to-group == 'ExpiredAccounts')

   {

        drop();

   }

The 

rcpt-to-group

 rule is message-based. If a message has multiple recipients, 

only one recipient has to match the rule for the specified action to affect the 
message to all recipients. 

The 

mail-from

 rule selects those messages where the Envelope Sender matches 

the given regular expression. For example, the following filter immediately 
delivers any message sent by 

admin@yourdomain.com

.

        drop();
