    I host and run multiple servers. I just started to use Jot Form, When I send test emails I get this following email. I can turn off SMTP Authorization required on my end and we get the forms. But I need to be able to require email authorization via SMTP for my customers, port 25 and theiur username and password.

    Here is the erorr.. Any way around this?

    The original message was received at Mon, 6 Jun 2011 10:06:35 -0400
    from localhost [] (may be forged)

    ----- The following addresses had permanent fatal errors -----

    (reason: 550 Authentication is required for relay)

    ----- Transcript of session follows -----
    ... while talking to
    >>> MAIL From: SIZE=3391
    <<< 550 Authentication is required for relay
    554 5.0.0 Service unavailable

    Again, I can turn this off, but I have a really good setup for spam protection and so forth. I would like to know if there is any other way around this?

    When sending test emails, the email notification will be masked and will use the email address that you have set in your Jotform account.  This is the one that's causing your test submissions to be filtered out by your anti-spam filter. 

    For security reasons many SMTP servers, especially outside internal network, reject all unrecognized connections and display relaying denied message. Unfortunately,  Email relay authentication is not yet available in Jotform's email alert features.

    But, with the actual setting that you have (you have used as your sender), I do believe your form notifications will properly land in your inbox.  In addition, you might want to add to your anti-spam exceptions.  Adding the email address to your contact list might also help.

    I will also submit a ticket to let our developers know about this issue.

    If you have other questions or concerns, please let us know.

    When you use for your forms we do not use your SMTP server to send emails. The emails are sent from our own servers. So, I don't think the messages you see on your logs have anything to do with the forms. 

    If this is a JotForm Application question please do not post it here. Send us an email instead.
