The mailing list for listmasters using Sympa

["Shane H. Wilson" <address@concealed>]

Thanks for your help, it turned out I didn't have any headers or footers 
defined, but I did find a solution to my problem and I wanted to share it 
with the list.

I had had the same issue with Mailman and that was part of the reason for 
looking at Sympa.  After seeing what Sympa can do, I think I'll stay.  I 
finally found that if I sent the same email directly to a Gmail account 
(without going through a list of any kind) I was having the same issue of the 
message being converted to plain text.  I had never noticed this behavior, 
because I don't think I had ever tried it and I'd never had a user report the 
issue before.  At that point it isn't a problem with Sympa or Mailman so I 
looked to Outlook 2011 again and I found the following web site with the 
solution.

http://www.officeformachelp.com/2011/05/exchange-mail-sent-as-html-in-outlook-2011-is-received-as-plain-text/

It theorizes that during an Exchange upgrade (which fits with us) the 
"contenttype" was set to MimeText and it should be MimeHtmlText.  This issue 
only affected OWA and Outlook 2011 (MAC), all Windows Outlook (2003, 2007, 
2010, 2013) were unaffected by this setting.  It also only affected OWA and 
Outlook 2011 (MAC) if the message was going to a system outside of our 
Exchange installation, anything other than @centre.edu (in our case).

The PowerShell to correct the problem is: get-remotedomain | set-remotedomain 
-ContentType MimeHtmlText

I hope this helps someone else!

Are your lists configured to add a header or footer?  This can cause some 
changes to the MIME type.  If Outlook 2010 is sending in Mime 
multipart/alternative then it mights append to the text part or do nothing; 
if your Outlook 2011 is sending in ms/tnef format you might end up with a 
mime/multipart containing the tnef and text.  Not sure what it will do then.

Try removing any defined headers/footers and see if it continues to do this.
