Cfrgtkky

I try to build contact email form in django using send_mail() function. It works fine in test environment but not in production. On submitting the form I get Server Error (500) in the browser. I receive django error reporting email with the below:

Exception Type: SMTPDataError
Exception Value: (550, b'Incorrect sender header (LOCAL)')

In settings I am using same email address for error reporting and for email form so it works in one case but not in the other. What does the above error mean? Any idea how to fix it?

kontakt.html

<form method="post">

    {% csrf_token %}

    {{ form.non_field_errors }}

    <div class="fieldWrapper">

        {{ form.from_email.errors }}

        <label for="{{ form.from_email.id_for_label }}">Email:</label><br/>

        {{ form.from_email }}

    </div>

    <div class="fieldWrapper">

        {{ form.subject.errors }}

        <label for="{{ form.subject.id_for_label }}">Subject:</label><br/>

        {{ form.subject }}

    </div>

    <div class="fieldWrapper">

        {{ form.message.errors }}

        <label for="{{ form.message.id_for_label }}">Message:</label><br/>

        {{ form.message }}

    </div>

    <div class="form-actions">

      <button type="submit" class="btn btn-success">Submit</button>

    </div>

</form>
