After years of developing the ActiveSync library, I have settled on  
using "Nine" as the main testing platform for Android - it is, by far,  
the most complete and best implementation I have found. I also  
periodically test native Android and Samsung's clients as well. Nine  
is not "non-commercial", but does offer a free trial that should be  
long enough for you to see that attachments work.

I have no experience with Jolla OS and have never tested our  
ActiveSync code against it. If I can easily get an emulator running I  
can look to see if I can reproduce the issue.

To further debug this issue on your end, we need details of the Horde  
-> Device connection. It may also be beneficial to obtain a network  
capture.

To enable debugging, see instructions contained in the ActiveSync  
section of Horde's configuration. Also, see  
http://wiki.horde.org/ActiveSync for more details.

Debugging should not be enabled on a production server,   Attach/post  
only the portion of the log that directly deals with the problem  
reported (it may be simplest to clear the log file and then perform  
the event that causes the error).
