Are these the same email? Is the Android log from an ActiveSync client  
or just a "normal" email client on the device?

I have no idea why this would happen for one ActiveSync client vs a  
different one, the SENDMAIL ActiveSync command is fairly straight  
forward and doesn't differ for different clients. Essentially we do  
some sanity checks and (at least for new mails, not replies) just sent  
the email through Horde's configured SMTP mailer.  I'd probably need a  
detailed ActiveSync log of the SENDMAIL command from the iOS device to  
see what it is sending to rule out (or fix) anything in our code.
