We just tested it again on Outlook Express, using XP and 98, and it came through fine. We also tried it on Hotmail, Yahoo and Apple's Mail, and there weren't any problems.

Hagbard, can you tell me where you saw that you need to keep headers all together? I ask because that's new to me, and when sending a multipart email (as we do with MilesLink), you have to separate the header's content-type in order to serve both text and html within the same email.

Sorry about the formatting problems some of you are having, but we can't duplicate the error on our end.
