I recently migrated webservers and have run into problems with a PHP
application that sends HTML emails to a mailing list. Outlook seems to
have no trouble rendering the email, but they show up as blank
messages in the Mac OS X mail client.
The old server ran apache 1.3.26, php4 and SMTP locally via sendmail.
The new server also runs apache 1.3.26 and php4 but SMTP is handled
externally by another server running exim. The new webserver runs
exim localally as well. All three boxes run Debian Woody.
The only difference I see in email that the application sends on the
two machines send is in the ordering of the headers. Here's what they
look like in email from old server (which sends the properly rendered
email):

And here is a header from the broken server:
