The issue you referenced affected Horde Git master which refers to the  
newer Horde 4 code. I do assume you are still on Horde 3.

And since you mentioned that you only see the problem on mail you  
copied over from an old server I'm pretty certain the problem  
originates from the server side. Horde could do a better job catching  
the problem but in principle the error indicates that the mails are  
broken and should get fixed.

Cheers,

Gunnar
