Having issues with Postal sending out message_id as xxxxxx@hostname rather than [email protected]

[ikatheria]

Postal is great tool.... but when I send the email then under the header is it always showing message_id with hostname which is set in postal.yml file but due to this emails are going to spam... is there any way to change the message_id with domain name rather than hostname?
