501 Error with email processor

[Ethan Gruber]

Hi all,

I am attempting to send an email with the oxf:email processor. I believe my input XML is set up correctly, but I'm getting the following error trying to send the email:

501 Syntax: HELO hostname in oxf:/apps/ceramics/xpl/xforms/send-email.xpl line 8 (javax.mail.MessagingException)

Postfix is installed, and I have logged onto the server and successfully sent an email over command line by following the traditional telnet commands (https://workaround.org/ispmail/lenny/test-mail-through-telnet).

I have found that you get this 501 error if you do not identify your own hostname, for example:

Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 servername ESMTP Postfix (Ubuntu)
helo
501 Syntax: HELO hostname

My /etc/hosts file has a hostname in it. Any ideas? Is this a problem with javax.mail.MessagingException not getting the hostname properly and identifying itself with the mail server, or is this a misconfiguration within my XPL?

Thanks,
Ethan

Hi Ethan,

I don't remember seeing this in the past, so this might be due to you using
the email processor with a config we haven't tried before. Would you be able
to share with what are the inputs you provide to the email processor, so I
can try this here?

Also, could you paste the whole Java stack trace?

Alex

Hi Alex,

Here's the XPL: https://github.com/kerameikos/framework/blob/master/xpl/xforms/send-email.xpl

I am calling the XPL within the XForms app, passing in #email-input. I am returning #email-input as the output data back to the XForms app, as I got an error when xxforms:call-xpl failed to include an output.

The XForms app is at https://github.com/kerameikos/framework/blob/master/xforms/invite.xhtml. It is fairly straightforward. It accepts an email address in the form, and a trigger then sends an email to this address.

<xforms:trigger bind="invite-trigger">

<xforms:label><span class="glyphicon glyphicon-envelope"></span>Send Invitation</xforms:label>

<xforms:action ev:event="DOMActivate">

<!-- send email -->

<xforms:setvalue ref="instance('email-input')/body/html/body/p/a/@href" value="concat(instance('config')/url, 'signup?auth=', $hash)"/>

<xforms:setvalue ref="instance('email-input')/from/email" value="instance('config')/admin_email_from"/>

<xforms:setvalue ref="instance('email-input')/from/name" value="instance('config')/admin_email_from"/>

<xforms:setvalue ref="instance('email-input')/to/email" value="instance('email')"/>

<xforms:setvalue ref="instance('email-input')/to/name" value="instance('email')"/>

<xforms:insert nodeset="instance('dump')"

origin="xxforms:call-xpl('oxf:/apps/ceramics/xpl/xforms/send-email.xpl', 'email-input', instance('email-input'), 'data')"/>

</xforms:action>

</xforms:trigger>

Hi Ethan,

And I imagine you used properties to setup the SMTP host (and possibly the
username/password) to use? Is that a publically accessible SMTP server? If
it is, could you add a debug on the data input of your email processor, and
give me the properties you're using, so I can try to run this locally and
reproduce the issue?

Alex
