Ive recently created a multipart/alternative email engine for a client to send TEXT/HTML emails out in a single mail.
All seemed to be going fine; Outlook on my POP Account viewed the contents fine, and Hotmail, Mail.com. Most of my original recipients responded that they could see either the TEXT or the HTML.
Recently though the client has begun sending the mails to users OF MS Exchange Server. When testing with MS Exchage I have noticed that it tries to convert the HTML to TEXT format, although there is a TEXT element to the email. It also does a pretty shabby job of the conversion.
I have now been testing and sending different headers in the mails. All of which has made no difference at all.
Has anybody else had similar MS Exchange problems and has anybody got any tips for me to overcome this.
NOTE: The best solution I have so far is to place the TEXT body of the email after HTML Body. MS Exchange users then see a well formatted TEXT email, but so do many of the previous recipients who prieviously saw HTML.
