E-mail Header | Content-Type Confusion

Gary_Kambic

Hi Guys,

I tried sending out this newsltter the otherday to over 200 people and I received several e-mails back telling me they couldn't make sense of it. They were nice enough to send the header and e-mail back to me:

Content-Type: multipart/alternative; boundary = Multipart_Boundary_xR419e100c6121cx

This is a multi-part message in MIME encoded format.

--Multipart_Boundary_xR419e100c6121cx
Content-Type: text/plain; charset=ISO-8859-1
Content-Transfer-Encoding: base64

Any thoughts as to why this is happening with only select people?
One of the people is using AOL so I added the text/x-aol header. I'm not surethat will help. I still need to test the x-aol header. The other two were using other ISPs to connect, not AOL.

Any help or feedback would be appreciated.
