Error sending the reservation

Hallo dear Support,

we use your plugin. And this is amazing. Easy to use.

We use the contact form for reservation, and we got some problems:

– we modified our reservation form, so the user can choose the location, and the reservation will send automatically to the right e-mail

– It works before but now its show an “error” u see it in red: “There was an error trying to send your message. Please try again later.”

– We followed the steps showing on the website of contact form 7
– The Error in the backend under the tab “Mail” was showed the hole time, and it works before on the frontend: “!(configuration error) Invalid mailbox syntax is used.”

Hear is the code:

<div class=”mkdf-cf7-rf”>

<label> Standort:[select your-recipient “Grunewald (Clayallee 1,
14195 Berlin)|[email protected]” “Mitte (Albrechtstra?e 13,
10117 Berlin)|[email protected]”]</label>
<label> Event Datum:[date* your-date min:2020-01-02 max:2050-12-31 class:required “2020-01-01″]</label>

<div class=”mkdf-cf7-rf-btn”>
<div class=”mkdf-cf7-rf-btn-inner”>
[submit “Reservierung Absenden”]
</div>
</div>
