I got several reports about destroyed attachments in the forum. All of the
users used a linux and all of them used an OpenSSL Lib 1.0.1c/d/e - so
1.0.1f is recommended (but not tested!). I know 1.0.2c is working well
with Net::SSLeay 1.72.

Betreff: Re: [Assp-test] TLS problems of connectivity?
Ok, anyway to debug log this in anyway to resolve Whats wrong?
Since I have one client running Thunderbird on Windows 10 which gets this
problem more or less everytime he attaches a file(on Any Type of internet
Connection) I should be able to get a result quite fast.
We run assp on latest ubuntu 14.04 LTS with latest patches from ubuntu so
the version of Openssl-lib should be safe, allthoug not latest version,
right?
