<h3>Number of initial servers (NBRSVR)</h3>
|

<p>Specifies the number of POP mail server jobs to start when POP is started by either the Start TCP/IP (STRTCP) command or the Start TCP/IP Server (STRTCPSVR) command. These jobs allow new clients to connect to the server without having to wait for the overhead associated with starting a new job. The server tries to keep at least this number of jobs available for connecting to new clients as the number of connected clients changes. This is a performance enhancement for the POP mail server that reduces the system overhead each time a client connects.

<p>Specifies whether or not to force conversion of mail to or from the ASCII CCSID specified on the CCSID parameter. This configured parameter is a global parameter; once you set it to *ALWAYS, it dictates the CCSID that all EBCDIC-to-ASCII mail will use. This parameter should only be set to *ALWAYS if there is a requirement to limit the character set. This should be communicated to all clients requiring mail interchange, particularly where language differences could cause a loss of certain language-specific symbols.
