Hello,

I'm somewhat of a MIME and Postfix newbie, so I hope that my question come
across clear. I am developing a PHP script that dishes out HTML newsletters
in a MIME multipart/alternative format. The script works great, but some
users have been complaining that the MIME formatted emails are reaching them
with corrupted headers (so that they are read as plain text - a big mess!).
All these users have virtual email accounts that use Postfix as the MTA. It
seems that when postfix handles the email for the virtual address it messes
with the header. Any idea why Postfix would do this?

Thanks,

Example Header (it looks like Postfix adds a line feed between
"Content-Type" and "From")
