The 

smime-gateway-deferred

 action performs an S/MIME signing or encryption of the message using 

the specified sending profile during the delivery. This means that the message continues to the next stage 
of processing, and when all processing is complete, the message is signed or encrypted and delivered.

The following filter performs an S/MIME encryption on all the outgoing messages from a particular 
sender during the delivery:

smime-deferred:if(mail-from == 

"user@example.com"){smime-gateway-deferred("smime-encrypt");}

The 

smime-gateway

 action performs an S/MIME signing or encryption using the specified sending 

profile and delivers the message, skipping any further processing.

The following filter performs an S/MIME signing on all the outgoing messages from a particular sender 
and delivers them immediately:

smime-deliver-now:if(mail-from == "user@example.com"){smime-gateway("smime-sign");}

The 

notify

 and 

notify-copy

 actions send an email summary of the message to the specified email 

address. The 

notify-copy

 action also sends a copy of the original message, similar to the 

bcc-scan

 

action. The notification summary contains:

The contents of the Envelope Sender and Envelope Recipient (

MAIL FROM

 and 

RCPT TO

) directives 

from the mail transfer protocol conversation for the message. 

The message headers of the message. 

The name of the message filter that matched the message. 

You can specify the recipient, subject line, from address, and notification template. the following filter 
selects messages with sizes larger than 4 megabytes, sends a notification email of each matching 
message to 

admin@example.com

, and finally discards the message:

Or

bigFilter:

   if(body-size >= 4M)

   {

        notify('admin@example.com');

        drop();

   }

bigFilterCopy:

   if(body-size >= 4M)
