Hi

I'm looking at the code and can see that the sending of these emails is done using Ajax.

The iform/client_helpers/prebuilt_forms/js/verification_4.js script has a sendEmail() function which hands the email to the server which processes it using the ajax_email() function in iform/client_helpers/prebuilt_forms/verification_4.php

The server responds with 'OK' or 'Fail' according to whether it thinks the mail has been sent. You should be able to use browser tools to inspect this network exchange. Ensure the information about the email looks sensible. If you are getting "The email was sent successfully" message this indicates that the server responded with 'OK'.

As the PHP documentation says, the mail() function used by the iform module "Returns TRUE if the mail was successfully accepted for delivery, FALSE otherwise. It is important to note that just because the mail was accepted for delivery, it does NOT mean the mail will actually reach the intended destination."

This function sends mail according to configuration settings in php.ini which is also the default Drupal behaviour. It is possible to use other mail-sending methods in Drupal e.g. by using a module like https://www.drupal.org/project/smtp. Do you do anything like that? If so, it could explain why Drupal can send email but the iform module is failing.

Hi Alice,

If you go to the Drupal menu item Reports>Status Report (admin/reports/status), scroll down to the PHP entry and click the more information link (admin/reports/status/php) you get to see the php.ini settings.

Perhaps there would be a mail server log to explain why the messages aren't being sent.

Hi

The reason for word-wrapping is to meet the specification for email and is not just about human readability so there could be negative effects. (Note, because it is an html message, to introduce line breaks for human readability we would have to use '<br/>' instead of the \n which is actually being used.)

The PHP documentation says of the body text that "Each line should be separated with a CRLF (\r\n). Lines should not be larger than 70 characters."

Is your problem also resolved by

wordwrap($emailBody, 70, "\r\n")

There also seems to be variability depending on the message transfer agent

Looking at the way Drupal does it, I see the comment

Quite a muddle!
