Hi,
Im running an application sending quite a few emails to members. Im building the emails with your every day ActionMailer builders, setting the content\_type to "text/html" and charset to "utf-8".
Now im hearing reports from some of our members that the emails show up as plain html-text in their clients. One such case is a user running the DWmail web based email client. ([http://www.dominion-web.com/products/dwmail/](http://www.dominion-web.com/products/dwmail/)) The website states that the client is supporting html mail, and the user in question doesnt experience the problem with other distributors of html-mail.
Could this be related to some rails-issue, and if so are there any tickets in the track?
Or, could i build my emails in some other way to extend the compability?
Thanks, Richard Johansson richard.johansson@gmail.com

Hi,
sending HTML mail (half offtopic here I guess) is very fragile. Here's all the headers that I \*had\* to use to make all webmail clients, even the totall broken IncrediMail & Co, and IMP (which is extremely anal retentive about standards, but at least \*right\*) display my mails correctly.
Content-Type: text/html; Charset=utf-8 MIME-Version: 1.0
The "Charset" has to be capital C and indented with a TAB or 8 spaces (otherwise some webmail clients choke on the mail). The MIME-Version: 1.0 is required by at least IMP. Some won't display the mail if it doesn't have a correctly formatted From: and To: header - "From: undisclosed-recipients:;" for example, has to have colon AND semicolon.
But my guess is that you forgot MIME-Version. 😉
