Blat 321, der SMTP-Mailer, 64bit hängt

Hello Administratoren,

I am trying to send automated mails via blat, unfortunately the system stucks.

The details:
Blat 321 64 bit, actual version, downloaded 2014-07-14, running on Windows Server 2012 R2.
The batch file:

set BlatProg=C:\Windows\...\Blat.exe

set to_Mail=*
set my_Mail=*
set Mail_Server=*
set Mail_Server_Password=*
set Mail_Server_Login=***

call %BlatProg% -to %to_eMail% -f %my_eMail% -server %Mail_Server% -u %Mail_Server_Login% -pw %Mail_Server_Password% - debug -subject enemenemuh

The effect: The batch file is executed and hangs after echoing the command line and the prompt: ‘Blat v3.2.1 (build : May 28 2014) / 64-bit Windows SMTP only, Unicode’. Debug information is not available. ^C is accepted and prompts 'Cancel batch file Y/N?'

Has anybody got an idea of how to solve the problem?

Thanks in advance!
