I've dug through any/all mail logs (using postfix).  The mail is NOT  
being sent to the SMTP server.  This is on IOS, I don't have another  
device handy to try.  I CAN send fine using IMP/Dimp and using mutt by  
only having the BCC or CC line set with the To line empty.  It doesn't  
appear to be a local error, but something funky with Apple, probably?   
I note that there's a configuration entry for Active Sync logging (  
$conf[activesync][logging][path]).  I have this set to a file, but the  
file is never generated?  Trying to get more detail out of this error.

I have two other "ERORRS" showing in my horde.log, but these occur  
when devices are just checking in and not doing any sending.  It would  
be interesting to know what they are, but they don't appear to be  
impacting this.

Other errors are:
