Issue

• __define_smtp_conn_string() method in the MailServer class should be moved to the Helper class for having a better separation of concerns

Issue:

• The message originator class doesn't contain a subject.
• This will increase the chances that our email will go straight to spam and will be never read by the final user.

Potential Solution:

• Add a new private method to retrieve the subject
• The subject should contain the ages of the recipient_name to better personalise the email
