Missing Notification Mails

Hello
my contact forms stopped sending notification mails to the webmaster. The user submitting the message still gets a confirmation though. But the webmaster does not receive a notification for new submission.

In the email settings I have put
Trip_organizer,[email protected];[email protected]

but these guys do not get anything. The new entry is in the database but no notificatio In the past they used to get notifications. What I did yesterday was to copy the settings of an existing form (which used to send mail notifications to the webmaster) to a new form. And this is all changes I made…. but all other forms including the new one do not send notifications any more…

I have tried putting a single email address in the email settings without any other text like this
[email protected]
but still no notification to [email protected]

I do not know if this last change caused the issue or it existed before I did the copy.

Any ideas what could have gone wrong?

Thank you
Pavel
