Error if port-entry is left empty (when adding server with SSL connection) #20
Description
If the port field is not filled out, NewsReader should try to connect to the standard ports (119 for unencrypted connections, 563 for encrypted connections).
If a new server gets added and the port field is left blank, the test connection fails, if connecting via SSL. If you fill out the port field with the standard port (563) it works.
