Check the HAT and use the ESA as relay specifying the email server.

Take a look to this document:

Hi Wajid

Hi Wajid

How r u trying to send the e-mail. If you just want to send a test email via ironing itself using CLI, you can use the telnet commands for it ehlo or helo .First of all you need to have listeners configured for inbound /outbound connection

Before make sure u have port 25 is open incase of any firewall in between.

Hi Wajid,

Hi Wajid,

To allow emails to be send outbound your exchange or relay server would need to point to one of the listeners configured on the ESA.

The listener should be configured with a sendergroup with Relay action, default named Relaylist.

Once the IP is added to the HAT Relaylist the connections from that server would be treated as outbound and emails should be delivered using SMTP routes or DNS lookups.

You can also add a desktop IP for testing to the HAT Relaylist and use telnet to send emails as mentioned in the below article.
