if I enable at /etc/amavisd/amavisd.conf:

$tls_security_level_out = 'may';

I got following WARNING inside my /var/log/maillog from AMaViSd-new:

Oct 25 07:32:34 server70 amavis[5115]: (05115-01) _WARN:  
Using the default of SSL_verify_mode of SSL_VERIFY_NONE for client\n  
is deprecated! Please set SSL_verify_mode to SSL_VERIFY_PEER\n  
together with SSL_ca_file|SSL_ca_path for verification.\n If you  
really don't want to verify the certificate and keep the\n connection  
open to Man-In-The-Middle attacks please set\n SSL_verify_mode  
explicitly to SSL_VERIFY_NONE in your  
application.\n*******************************************************************\n  at /usr/sbin/amavisd line  

Maybe there are some problems on CentOS-7 with the defaults for SSL at  
IO::Socket::SSL ...?

Sorry, I'm not a perl programmer...

Thanks for the help!
