Change project fullname in Email header

[Paul Willard]

I setup a project and Called it Helpdesk, and an email address support@domain

Later on I renamed the project to "Company Helpdesk", and continued using the email support@domain

When an initial ticket comes in the email from address hasn't changed.

Looking at the headers:

Date: Fri, 10 Aug 2018 14:49:00 +1200 Subject: HD-93 Where does the initial email come from ?
From: Helpdesk <support@domain>
To: "paul@domain2" <paul@domain2>
Message-ID: ..... (truncated)

I can't see anywhere to change this?

I've tried exporting and looking through entities.xml but it's not obvious where to change this.

Can someone help?

My solution to the question:

change JSD to use localhost postfix.

create file /etc/postfix/header_checks

/^From:\ Helpdesk.*/   REPLACE From: Company Support <support@domain>

run: postmap hash:/etc/postfix/header_checks

reload postfix.

Not great, but it works
