It's not superfluous.

Moving a member to another group does not automatically reset the admin emails option. Try it yourself: Chcek the settings of a regular member, then move that regular member to a COPPA group or Banned Users group - what happens to the email and PM settings?

There are several kinds of emails that fall under the 'email from administrators' category:
1) email sent trough the 'send email to users' page in admincp.

But for this function the usergroups to send to need to be selected. So for this function, it is not needed to turn off 'email from administrators'. Its highly unlikely someone will send a bulk mail to 'users awaiting email confirmation'.

2) birthday emails. Yesterday I did not think about birthday emails. This kind of email makes it necessary to turn off 'email from administrators' for accounts with bouncing email addresses.

Are there other kinds of emails that are blocked by turning off 'email from administrators' ?

:confused:

If the admin email option is unselected, it affects ALL emails from admins.

I second this.
I had the same issue, with a user who although being in Bounced usergroup, he was sent a Happy Birthday email, which normally bounced back as undelivered.

I hope you may update this great hack to reflect this setting

:confused:

This add-on already does that.

Which are? That was the question.

If I turn birthday emails off and if I do not send any email trough the function in adminCP > Users > send email to users to members in the bounce group, then will any other admin emails be sent to users in the bounce group?

I'm just trying to find out what turning off the 'email from administrators' function exactly does. Which functions does it block?

Another question:

If a user is deactivated, then the user is moved to Users Awaiting Email Confirmation.
In the scheduled task manager you will find this vbulletin cron process:
Does this cron affect users that are in the Users Awaiting Email Confirmation usergroup?
i.e. does this only send at day 2 and day 6 of registration or does it send at day 1 and day 5 after the account is managed for bouncing email?

Sorry for all the seemingly trivial questions, but I have been working for over a month, on automating this whole process and am trying to do it right.

I think we need also to update bouncing member's "Receive Friend Request Notification" setting to NO. How to do that?

will it works with 4.7 and above.

I'd expect so, but cant confirm it above vb 4.0.3 yet.
