The Change POP Mail Server Attributes (CHGPOPA) command is used to change the Post Office Protocol (POP) Version 3 Mail Server attributes. The changes take effect the next time the POP3 server is started either by the Start TCP/IP (STRTCP) command or by the Start TCP/IP Server (STRTCPSVR) command.

Specifies whether to automatically start the POP mail server when TCP/IP is started by running the Start TCP/IP (STRTCP) command, or the Start TCP/IP Server (STRTCPSVR) command with SERVER(*AUTOSTART) specified. When the POP mail server is started by running the STRTCPSVR command, and SERVER(*AUTOSTART) is not specified, this parameter is ignored and the POP mail server is started regardless of the value of this parameter. If STRTCPSVR *POP is specified, and the POP server is already running, then an additional server job is started.
| Top |
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.
| Top |
Specifies the number of seconds of inactivity between the client and server before the server assumes the client has stopped communicating and disconnects from the client. When this event occurs the server does not delete any mail in the user's mail box to ensure that mail is not lost.
| Top |
Specifies the number of kilobytes that will be used for partial message blocks when the mail message exceeds this count. This is used only for remote mail delivery. This is a network parameter and is determined by the capacities of the network gateways you are connected to. Changes to this parameter take effect immediately; you do not need to restart the POP server.
| Top |
Specifies the MIME coded-character set identifier (CCSID) conversion parameters for text data. You must restart the mail server framework (using the STRMSF command) for changes to this parameter to take effect.
Element 1: Coded character set identifier
CCSID value to be used for single-byte character set (SBCS) and some mixed-byte character set (MBCS) ASCII translations when doing ASCII-to-EBCDIC and EBCDIC-to-ASCII mapping.
MIME Standard: US-ASCII Name: US English EBCDIC CCSID: 00500
MIME Standard: ISO-8859-1 Name: Latin-1 EBCDIC CCSID: 00500
MIME Standard: ISO-8859-2 Name: Latin-2 EBCDIC CCSID: 870
MIME Standard: ISO-8859-5 Name: Cyrillic EBCDIC CCSID: 01025
MIME Standard: ISO-8859-6 Name: Arabic EBCDIC CCSID: 00420
MIME Standard: ISO-8859-7 Name: Greek EBCDIC CCSID: 00875
MIME Standard: ISO-8859-8 Name: Hebrew EBCDIC CCSID: 00424
MIME Standard: ISO-8859-9 Name: Latin-5 EBCDIC CCSID: 01026
MIME Standard: ISO-8859-15 Name: Latin-9 EBCDIC CCSIDs: 01140-1149
MIME Standard: ISO-2022-JP Name: Japan MBCS EBCDIC CCSID: 05026
Element 2: When to use
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.

Example 1: Setting an Inactivity Timeout
CHGPOPA INACTTIMO(700)
This command sets the time of 700 seconds that the POP server will wait before assuming the client has stopped communicating. After this time the server will disconnect from the client. No mail will be deleted.
Example 2: Setting a Default CCSID
CHGPOPA MIMECCSID(923 *BESTFIT)
This command sets the CCSID 923 to be used for conversions, if the CCSID cannot be determined from the mail. This CCSID contains the Euro character.
