Indeed, I was going off this old ticket[1], though the difference is  
that person got raw base64 in the reply quote; I get nothing.

PHP version is 4.3.1; currently I can (if necessary) upgrade to a  
later 4.3 version, but I'm not able to go beyond that without full  
code-review of the other application on the same server.

Horde platform is groupware-H5 pear on Windows/Apache2.2, all up to  
date excepting imp-6.1.5 (and I see nothing in changelog that might  
address this).

Thanks,
