Compatibility with SMTP authentication

I am pretty sure that webforms has a solution and it just needs to be ported to this module.

Okay here is a patch without any tests.

To use short form (Windows friendly) from email addresses you need to...

• Go to Admin setting (/admin/structure/yamlform/settings)
• Open EMAIL DEFAULT SETTINGS
• Check ' Short format:' in 'Email address format'
• Click Save

@NYSolutions.com Please see if this fixes your problem.

So I am pretty sure the issue was that the YAML form module is attempting to provide support for sending HTML emails and this was blocking the SMTP module from handling emails send by the YAML form module.

Please test the attached patch. You can use the Status Report (/admin/reports/status) to confirm that the SMTP module is now handling sending out the YAML form module's emails.

It is probably because you have the SMTP module and YAML form module already enabled.

The attached patch includes an update hook that should address this. If not, please try reinstalling the SMTP module.

Hi all, this patch compatibility_with_smtp-2770071-10.patch is successfully applied to 8.x-1.x branch.
Thanks

@nysolutions Another approach is to checkout the feature branch.

https://www.drupal.org/node/2640714/git-instructions/2770071-smtp-authen...

The patch is not being applied correctly. Try the attached zip.

@AsadKamil Can you please test this patch using clean installation. You don't have to even configure the SMTP module. The key thing is the status message should say SMTP when both the YAML form and SMTP module is installed.

Using simplytest.me I was able to get the2770071-smtp-authentication-02 branch installed with the SMTP module and confirm that the status message has been updated.

Here the simplytest.me site, which is only available for 24 hours.

Just tried downloading the newest stable version of smtp - June 27th.

Sending a test message was fine. But once I tried submitting the message in the form I receive the following error.

Here is the error I am receiving -
Invalid address: You must provide at least one recipient email address. Invalid address: The website encountered an unexpected error. Please try again later.
RuntimeException: Failed to start the session because headers have already been sent

I think this issue might not be related to the YAML form. My patch and solution basically allowed the SMTP module to be used to send email. It is possible the YAML form module is sending incorrectly email values/headers to the SMTP module.

Are you able to to duplicate the error using just the Contact form?

This is the most recent version of core:
-smtp: current stable
-yamlform - 8.x-1.x

Yes I am able to send the test message. Everything looks great with the test and I have also confirmed that the messages are in fact being sent to both the user and the site account.

The only issue now is the error that shows up in the dialogue box after a submission.

Here is the most recent error:

This code is handling file attachments. I am probably passing a bad value to the SMTP module.

Does your form have a file upload?

Can up export your form, remove the emails, and upload it here? Here is video that walks you thru the best way to export a form. https://www.youtube.com/watch?v=ejzx4D0ldl0 Make sure to enable the YAML form devel module.

@jrockowitz: such great work !
Ok - I ran in the same problem and figured it out:

In EmailYamlFormHandler::getMessage() line 523ff there is

// Add attachments.
    if ($this->configuration['attachments'] && $this->supportsAttachments()) {
      $message['attachments'] = [];

Please add this

    else {
      $message['attachments'] = [];
    }

otherwise it comes to an error in SMTPMailSystem::mail() in line 438 because $message['params']['attachments'] = FALSE and not an empty array:

// Process mimemail attachments, which are prepared in mimemail_mail().
    if (isset($message['params']['attachments'])) {
      foreach ($message['params']['attachments'] as $attachment) {

Greetings from Cologne

If the attached patch passes all the test, I will just commit it.

Fixed! Please download or checkout the latest dev release.

Thats fast !! - and better than my solution :-)
Maybe its a cache-problem: the patch isnt in latest dev. I grabbed it with "drush dl yamlform --select" and downloaded it as zip. Strange...
Im sure this will work lateron.
