[Bug]: Email service is waiting for emails to go out forever

Existing issue

• I have searched the existing issues and found no duplicate.

Problem description

I created a fresh server end installed email.

Everything works, but when i send an email to postmaster@my_domain.com the email never reaches the predefined postmaster inbox, instead an additional email is queued and never leaves:

Every time i sent an email to postmaster, the number increases.

Is there a way to see and cancel those queued emails?

Steps to reproduce

see above

Environment

• OpenShip version/commit: 0.7.2
