ASA support SMTP proxy?

Does ASA support SMTP proxy? i am not sure if this is the right term but what i mean is like the cyberguard fw where they are entering all the valid email ids on the device and the firewall will not forward the packet to the smtp server if the email id is not one in the list.

thanks

Re: ASA support SMTP proxy?

If I'm correct, you need to configure ASA such that some specific email-ids only should be allowed to send mails through ASA.

You can do this on ASA, here is a example where only 3 email-ids are allowed to send mails through ASA (user1@cisco.com, user2@cisco.com, user3@cisco.com):

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

regex user1 "user1@cisco.com"

regex user2 "user2@cisco.com"

regex user3 "user3@cisco.com"

class-map type regex match-any allowed-senders

match regex user1

match regex user2

match regex user3

policy-map type inspect esmtp filter-senders

parameters

match not sender-address regex class allowed-senders

reset log

match ehlo-reply-parameter others

mask

policy-map global_policy

class inspection_default

inspect esmtp filter-senders

service-policy global_policy global

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

Here is a link which you can refer to:

http://www.cisco.com/en/US/docs/security/asa/asa80/configuration/guide/mpc.html

Hope this helps.

Regards,

Vibhor.
