Hi,

You can create new listener with port 587 from:
ESA>GUI>Network>Listeners>Add Listener

Make sure that the RAT is configured correctly and its on the right interface.

Normally this port should be open for the mail server, but you can set it up from there, if you would like to.

Below document links will help you provide more insights on the same:

I hope the above helps.
