"From" field sent in auto response email uses select list keys instead of labels

Hi there, yep this is the right place for Webform questions.

I haven't heard of this problem happening before, especially with just the string "email" instead of an actual e-mail address. Do you have any other modules installed with affect e-mail? What about any custom modules that you've written for your site? Since any module has the opportunity to modify outgoing e-mails through hook_email(), the problem could likely be a module conflict.

A simple thing you might try is switching Webform to use the "short" e-mail format instead of the full format. There is a setting for this under Config -> Content authoring -> Webform settings, in the "Advanced Options" fieldset. Some times using the shorter e-mail format helps some servers send e-mail correctly.

Could you try sending yourself an e-mail from the site using the password reset form? Perhaps this is a hosting issue. If you find that all e-mail addresses are getting mangled on the way out, you might look into using an external mail server (like Gmail) to send your mail using the SMTP module.

Any updates here? I'll probably marked this closed if it doesn't look like there's anything happening here. If you haven't already, taking a look over the many suggestions in #364673: Webform not sending e-mail (general troubleshooting, tips) may also help.

Hm, I think what I'm experiencing might be the same issue - or at least closely related:
Thankfully the feature #687606: Add conditional email sending feature was implemented recently and I was able to reconstruct my contact form so that the subject was preselected based on form url. It works like this:
Custom made contact form with the fields: Name, Your e-mail, Phone, Subject and Text. In addition I added the field "Destination" - a select options field containing a set of key|option pairs depending on who the customer wanted to contact. The Key|option list is something like this:

1|Alabama
2|Belgium
3|Croatia

Now, for sending the e-mails I added two entries on the /node/[node_id]/webform/emails page: one for a confirmation message to the customer and one for the Destination. The entry on the webform/emails page lists something like:

The Value of "Your e-mail" entry has the E-mail from address set to Component and "Destination" selected. The option/e-mail mapping looks like this:

Alabama|aaa@email.com
Belgium|bbb@email.com
Croatia|ccc@email.com

The E-mail from name field is set to Component: "Destination" too.

If I want the form preselected to send contact request to bbb@email.com I would use the local url: /contact/key=2 as the default value of the Destination field is set to [current-page:query:key]

The form works in the sense that e-mails are sent to the correct receipients, but when received it looks like the sender information is a little messed up. The from address looks like this:
username@myserverhost.com on behalf of 2 <bbb@email.com>
Why is this so? I would have expected something like
username@myserverhost.com on behalf of Belgium <bbb@email.com> am I right?

For the record: I'm running webform 7.x-4.0-alpha9

Thanks @stenjo for your report. This probably should have been filed as a separate issue considering it's against 4.x, but I appreciate the extensive and clear report of the problem.

Why is this so? I would have expected something like
username@myserverhost.com on behalf of Belgium am I right?

That indeed sounds like a bug. I'll see if I can reproduce it.

I reproduced the problem easily enough. This patch solves the problem by converting select list values to their labels when used as the FROM name in e-mails. Committed to 4.x branch. Thanks for the report!

thankyou @stenjo
