I’ve been actively ignoring all the traffic about recent problems with the Mailer Extension until today. I had done preliminary testing and nothing was throwing errors so I figured all was well before I released our converted site live. Now I’ve got a real and configured mail server behind the site to test against I discovered a problem. Though my forms return “email\_html” page parts and don’t also have an “email” part or anything like that, the email that I get in response is encapsulated in “text/plain” and won’t display at all in my email client unless I got to view Raw Source of message. The content of these forms and output email\_html parts have not been touched through this conversion. The below two emails are generated by each version of the Mailer thing respectively – Mailer Extension email in Pastie which shows-up as a blank message in my email client unless I look at the Raw Content of the message then I see this (\* note line 41): [http://pastie.caboo.se/37563](http://pastie.caboo.se/37563) Line 41: Content-Type: multipart/alternative; boundary=mimepart\_45c3ba4744994\_eb9…fdbb90756334 From the older Email Behavior which does display as expected in my email client (\* note line 33): [http://pastie.caboo.se/37567](http://pastie.caboo.se/37567) Line 33: Content-Type: multipart/mixed; boundary=mimepart\_4581bf35ab0e3\_657…fdbbd21a01862 I started digging into the Mailer Extension code but thought I’d ask around to see if anyone knows enough about email formats or the code in the extension to give me a hand. This sure seems like a bug to me. Any help is appreciated. Yey! We’re finally have everything converted-over to mental (just in- time to miss the first RC 😉 Loren J.

Loren, That was my change. Back last March when I was developing a Rails application that needed to send email, I dissected various gracefully-degrading emails that I got in my inbox. I found that, for most email clients, the multipart/alternative type with a text/plain and a text/html part seemed to be the most compatible. I’m willing to change that assumption, however, and the code, if you have a better solution. I searched a lot and didn’t find any reliable reference for how they should be formatted, so I reverse-engineered it. Sean ---

Sean, Yeah since I wrote that message I’d done some looking around: > **[Sending HTML and Plain Text Email Simultaneously](https://www.practicalecommerce.com/html-email-multi)** > > With so many different smartphones and tablets, it’s important to be able to display your company's emails in the way that the mobile browser is best suited. Some mobile browsers will show your email in its full HTML form. Others will default to just... [http://www.freesoft.org/CIE/RFC/1521/18.htm](http://www.freesoft.org/CIE/RFC/1521/18.htm) And will look into it more this afternooon. I need to follow through the code and my page to see why my the plain text version is blank, as on first glance in the code it looks like it’d have a default list of the fields at least. Then I’ll look into why Mac Mail isn’t choosing the HTML version as it did in a multipart/mixed message… If I see any reason to change things in the code I’ll write-back with my suggestion. Right now as far as I can see the raw multipart/ alternative message looks correct except the missing plain/text content. Thanks, Loren ---

Oops, actually easier said then done… I’m checking out the Mailer Extension via svn:externals to Mental and will have to detach from the mothership to test this which I’ll do depending on your answer. The change of ordering that parts is a really straight forward swap at lines 256-262 of mailer\_page.rb I don’t know if it’ll solve my problem but if it needs to happen anyway… When do you think you’ll get to that?

That makes sense however it still doesn’t answer why the html version isn’t being preferred by Mac Mail (not checked with any other clients yet). . . I’ll rearrange the order of the parts and re-send to see that magically fixes it. L ---

Later today probably; I’ll be helping John and the rest of the core team with the 0.6 RC. Watch the changelogs at [http://dev.radiantcms.org/radiant/timeline](http://dev.radiantcms.org/radiant/timeline) if I don’t get back to you. Sean ---

Thanks and np, I forget, “this is the day” 🙂 Honestly I don’t think changing the order of the parts will fix my problem anyway, though it does look like it should happen anyway. ---

Finally, I manually re-arranged the plain and HTML parts in a test message and opened it up directly in Mac Mail. Yep… that definitely fixes it.
