No visible error when sending Receiver-Mail ends up in an exception

[twestner]

in https://github.com/in2code-de/powermail/blob/typo3-v13/Classes/Controller/FormController.php#L273 is the process:

• first send mail to sender
• then send mail to receiver

If an exception occures in generation-process of second mail, the user does not get a visual feedback of the failure.

=> The catch-Block catches the exception and writes the error into the log
=> no flash message is generated
=> the sender has already reached his confirmation but the recipient never gets any email

I agree. I also noticed this a while back. I think it might be a good idea to switch the order or at least make this configurable. However, it might be intentional as the sender email is more volatile as it is entered in the form. The receiver mail should be checked when form is created and should work. The mail to receiver might also fail with incorrect sender email.

You can however do some measures on your end, e.g.

• monitor email sending errors, e.g. in logs or by using extension pluswerk/mail-logger with additional watchdog. If sending fails, the receivers can be notified. If answers are stored in the database, the mails can be constructed from that.
• automatically check plugin configuration for consistency, e.g. receiver email (On our site the receiving emails should all be university emails which can be validated with the SMTP server)
