Well, challenging to me anyway :-P
Let me pick your brains for a bit. I have a newsletter php script, which is sending out html newsletters. Outlook/Outlook Express and the like show the newsletter just fine. Mail.com and other web mail clients show a big old white space where the newsletter should be.
Where would you start in finding the cause of this? Some history:
I've received other html newsletters in mail.com that display perfectly.
I can copy that same html code from the above newsletters, send it back to the same account with this script, and those emails are blank too.
When turning on all headers in mail.com, I have:
Content-Transfer-Encoding: 7bit
Content-Type: text/plain; charset="iso-8859-1"
where the html newsletter is supposed to display.
There doesn't look to be anything comparitively wrong with the headers to what Outlook generates and mail.com generates.
What're your thoughts? I'd appreciate any direction.
