Hallo Akeeba,
In Admin Tools (7.1.x) for Joomla 4 you can no longer save more than one email adress for sending email messages.
Admin Tools | Control Panel | Web Application Firewall | Configure WAF
Logging & reporting | Email this address on blocked request
If you try to save:,,
The saved item will be:, charlie
I see a tooltip (in Dutch) that a symbol ',' may not follow on '@' symbol.
It is always trimmed at the second @-symbol.
This is also for "Email this adress on successful backend login" and "Email this adress on failed administrator login"
In de latest manual "admin tools.pdf" on page 125 is still:
Email this address on blocked request
Enter one or more email addresses (separated by commas) which will get notified whenever a
request is blocked on your site. For example for one recipient only or,, for multiple
recipients. The email addresses need not be in the same domain name and don't even need to be
users of the site itself. Any email address will do.

Now that you mentioned it I can tell you immediately what the problem is. We have switched to Joomla 4 native forms. The email fields come with automatic server-side validation. I had forgotten about this. I will fix that for the next release. Thank you for the heads up!

Hallo Akeeba,

I see it has been solved in Admin Tools version 7.1.9:

Fixed [LOW] Regression: Multiple email addresses were not allowed in Configure WAF options.

I tested the new version and yes, I can now add more than one E-mail address and it will be saved.
Thank you!
