How to change the logo on the notifications' email address bar.

[Tully Team]

I've looked everywhere and can't figure out if there is a way to change the logo of our support@notifications email address. So when we respond to a customer's request, the email address shows our company logo.

Please refer to the image below. 

Thank you all in advance.

I think you have to change this in your Mail Program and not in jira.
If it it a company mail, your IT should change it in the LDAP user profile.
