Making changes in emails sent via OJS

I have a question regarding sending emails via OJS.

Our Editor would like that the subject line of the sent email
(when we use prepared emails) not to contain brackets [] at the begining, and he doesn’t want the url of our site to be displayed at the end of the text of the email (at the bottom).

How I can fix that?

Thank you very much.


The email signature is in Journal Setup, Step 1.4:
User Home → Journal Manager → Setup → 1. Details → 1.4 Email Identification

The prefixing of the Journal Initials in brackets on the subject line would be a code change. See:
