Sender E-Mail is sent to TYPO3 default email address

[r3h6]

TYPO3 v12.4 Powermail v11.2.0

1. Plugin is set up to send an email to the sender
2. Sender enters invalid email address, for example [email protected] (two dots)
3. Email is sent to the system default email address

Expected:

• If an email validation fails: Message in frontend
• Otherwise try to send to given email address instead of TYPO3 default address
