EMail Multi-part MIME recently starts failing.
Posted: Thu Jun 22, 2006 4:34 am
Hello all,
Performed a search on the forum but cannot find anything and have investigated on my own but cannot find anything wrong.
I have recently started looking at a problem reported with email sending. The php code for email has been used for ages without any change and only recently have we received notice that some users (I think, but can not confirm, using only Microsoft Outlook on Windows) now get email showing only "This is a multi-part message in MIME format". Using thunderbird and other mail clients seem to work with no problem. As this error has (to our knowlege) only recently started to occur so the real question I guess is...
QUESTION1 : Is there any Microsoft Update that modified Outlook Mail processing and possibly broke it according to what we use...
QUESTION2: does anyone know of an "MIME validator" or other debugging tool which I could pass mail messages through to see if they are correct and highlight potential problems when I get tasked with investigating this kind of problem ?
I have included the top of the MIME for informational use <!-- --> are used as placeholders only for display here. The actual mail is far longer and includes HTML, images etc.
