Description:

Add the ability to set a default BCC, so any mail that was not set with one, will get the default one (if set).
1 use case is to save all outgoing emails in a different email account for debugging and history preservation - with this feature it is much easier to achieve without changing 100's of email configurations

Steps to test this PR:

1. Load up this PR
2. Set a default BCC address in the email configuration section
3. Send out a test email and make sure it was sent to the bcc address as well. ( you will need to configure the email settings to something that will actually send out emails)
4. Create an email template, and set a different bcc email to it
5. Get the email to be sent out (in a flow) and make sure that it was bcc'd to the email specif address and not the default one

@escopecz @kuzmany can you please review and feedback?

full disclosure: I didn't write php for 7 years or so - actually had to google "php check if array is empty" :-)

Awesome product by the way!

[escopecz]

I don't see any issue with your code. Nice work! It just must be tested.

[regevbr]

@escopecz thanks!
Anything else needed on my part?

[escopecz]

Just patience. There is not so many testers.

Hi there!
It has been decided to not create any extra Mautic 2 minor versions (which means no more features in M2) knowing that Mautic 3 is coming very soon.

We now want to integrate your contribution in the Mautic 3 roadmap as 3.1.0 candidate.

How to do?

1. Check if your feature or enhancement is still missing and relevant in Mautic 3
2. If Yes: rebase your PR against the 3.x branch
3. If No: please consider closing your PR if you are absolutely sure that the feature has made it into Mautic 3 already

Please report results by commenting on your PR to make us administration easier.

You can more information on how to do all of that on this blog post "Getting you PR ready for Mautic 3".
