So it's in my opinion a good idea not to expect headers to be ordered and add headers in a way which doesn't conflict with a *possible* reordering. -- Greetz, lunqual - http://www.lunqual.de http://www.42pixels.de - Bilder http://www.rezeptbuch-pro.de - Software für den Destillateur -- http://mail.python.org/mailman/listinfo/python-list

First, Email-headers are unordered and every relay can, and probably will, rearrange them, add or delete headers. You therefore most definitely should not add any headers which are position-dependent. If you want to track mails somehow, add headers with timestamps.

Email module, how to add header to the top of an email?
I have been using the Email module and Message class for awhile, however I have been unable to find a way to add a header to the top of the email similar to what is done with Received: headers... the add_header method only appends to the bottom. Is there someway this can be done? Thanks David -- http://mail.python.org/mailman/listinfo/python-list
