We suggest to add a parameter in the configuration files or in the user interface to set the maximum number of concurrent connections on SMTP server in Qlik NPrinting. Not limiting the concurrent SMTP connections is creating troubles to some SMTP servers.
This idea was mentioned in the community, for example in https://community.qlik.com/t5/Qlik-NPrinting-Discussions/Email-send-out-fails-due-to-the-maximum-num...
