Configure the Adaptive Security Appliance to Support WebVPN
Configure WebVPN e-mail proxy

The mapi parameter enables or disables Microsoft Outlook/Exchange port forwarding at the group or user level and is only necessary if this feature is to be used .

Proxy servers are defined by entering the appropriate subcommand mode in global configuration mode . Proxy servers are available for POP3S, SMTPS, and IMAP4S.

Use the server command in the applicable e-mail proxy mode to specify a default e-mail proxy server . The Adaptive Security Appliance sends requests to the default e-mail server when the user connects to the e-mail proxy without specifying a server. If a default server is not configured, and a user does not specify a server, the security appliance returns an error.

Use the authentication-server-group command to specify the set of authentication servers to use with the e-mail proxy.

Use the authentication command to configure authentication methods for the e-mail proxy . To restore the default, aaa, use the no form of this command.

The example in Figure illustrates the various parameters that must be configured on each device. The main items of interest are the e-mail server address and port assignments entered on the e-mail client. These must match the ones configured on the Adaptive Security Appliance, not those configured on the e-mail server. In this example the username and password on the e-mail server and the ASA are the same, so no special delimiters need to be used on the e-mail client.
