Steps to reproduce:

1. Configure a fake SMTP server to see outgoing emails (e.g. FakeSMTP)
2. Log in as admin
3. Go to Control Panel > Instance settings > Email and under EMail sender change the default to something valid (see attached screenshot as an example)
4. Create a new message board and place it on a page
5. Go to Content & Data > Message boards > kebab menu > Configuration and under Email From configure the same name and address as in step 3 (in master this is automatically copied over)
6. Restart the portal (otherwise email sender changes do not take effect)
7. Sign in and create a new thread in the message board.
8. Open the thread and click on the flag icon to report it.
9. Select a category and fill in the captcha and click on report.

Actual behavior: Thank you for your report message Appear but outgoing mail still sent from invalid address ([email protected]) which will normally be blocked in a live environment resulting in the below warnings in the log:

WARN [liferay/mail-3][MailMessageListener:135] Email [email protected] will be ignored because it is included in mail.send.blacklist
WARN [liferay/mail-3][MailMessageListener:52] Skipping email because the sender is not specified

Expected behavior: Email notification sent to Admin about the reported message
