Mail from mendix

We're sending notifications from our app to users. Sometimes the mail isn't html. How can that be? We're using a java action send the mail away. Example of a mail in my outlook: Filter staat op 2010, maar niet alles van 2010 wordt getoond. MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="----=_Part_12_426008374.1288078572908" ------=_Part_12_426008374.1288078572908 Content-Type: multipart/alternative; boundary="----=_Part_13_212262720.1288078572908" ------=_Part_13_212262720.1288078572908 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 7bit

Content-Type: text/plain; charset="UTF-8"

Shouldn't it be Content-Type: text/html; ?

Update

Based on the Email module source, a MIME part with 'text/html' will be added if the HTML text is set. So it appears that either htmlMessage is empty, or that you did not list the full message.

Note however that 

   message.replace("\n", "<br/>");

does not turn your message magically into HTML! You need to encode all the text to valid html entities (there are useful functions for that in the apache.org libraries). So I can imagine that e-mail clients won't show your message as soon as it contains any special character, since you do NOT provide valid HTML.

Samet didn't post the entire mail content (see below), but the problem here wasn't the content of the mail (which did correctly contain a text/html part). The issue was a line break in the subject of the mail, which caused the mail not to recognized as a MIME message by the mail client.

The complete mail was:

From: ...
Send: Tuesday, October 26, 2010 9:36 AM
To: ...
Subject: Update action: Filter bij onkosten overzicht niet goed.
