Problem with SMTP

Hi,
I made a new contact form with ChronoForm V5. From the provider I have to send this via SMTP mail. If I want to send something via the contact form, I get this error:
Mailer Error: SMTP Error: The Following recipients failed: info@modevakschoolria.nl.
Does anyone know this board, I've tried everything but it does not work. Website: modevakschoolria.nl.
Regards, Wolf

Hi Wolf,

Are the To and From Email addresses different?

Bob

Hi Bob,
No, they are the same. I've tried, without result.

Wolf

Hi Wolf,

Then please make them different - that may well be the problem. Please see this FAQ

Hi Bob,
I have used two different emails:
info@modevakschoolria.nl and postmaster@modevakschoolria.nl
and get the following result:
Mailer Error: SMTP Error: The following recipients failed: info@modevakschoolria.nl
Mailer Error: SMTP Error: data not accepted.

Wolf

Hi Wolf,

Please check the FAQ I linked to. My best guess is that this will be something to do with the Mailer configuration if it is not accepting the mail address.

Bob
