Re: Simple XMOD form - Email SMTP Error: Mailbox Unavailable

Hi everyone,

In Host > Settings -  the Test Email button works OK !
It is using Basic Authentication with a Userid / password.

I'm using a DNN XMOD module form www.dnndev.com to send emails when a form is submitted
but I'm getting Event Viewer error when submitting the form.

Mailbox unavailable. The server response was: <xxx@crowncomputers.com> No such user here

Is there some security in the Email Server that would cause this ?

Code Below: xxx and yyy block out real email names

<form>
<controls>
<input ref="name">
<label>name</label>
</input>
<email target="xxx@crowncomputers.com" from="yyy@crowncomputers.com" subject="CrownHost DNN Email Test">
<content format="html">
<literal>
<h2>Test Email CrownHost DNN Site:</h2>
<p>Customer Name: <xmod:field name="name"/></p> <br />
</literal>
</content>
</email>
</controls>
</form>

But when submitting the test XMOD form, the Event Viewer error shows:

InnerException: Mailbox unavailable. The server response was: <xxx@crowncomputers.com> No such user here
FileName:
FileLineNumber: -1
FileColumnNumber: -1
Method:

Appreciate any ideas on how to resolve this ?

Thanks, LA Guy
 

I have been fighting a similar problem with a new DNN site for several days.  I finally found the fix today.

There is an interesting "glitch" in the Host Settings/SMTP page.  Select "Basic" for SMTP Authentication, which is needed by many SMTP servers, enter a Username and Password, and then click "Test", and everything works.  However, the Password is now BLANK.  If you now click "Update" , the information stored has a blank password.

If you enter the Username and Password, then click Update, the correct password is saved.

This should probably be fixed, no?

LA Guy, could this be your problem too?
