ZMAIL - Control the z/TPF Internet mail servers

Use this command to control the operation of the z/TPF Internet mail servers, which allow users, or mail clients, to send and retrieve Internet mail, also known as electronic mail (e-mail).

Requirements and restrictions

You can enter this command only when the z/TPF system is in CRAS state or higher.

Format

STARt

starts the appropriate z/TPF Internet mail server. If you do not specify an additional parameter, all the z/TPF Internet mail servers are started.

STOp

stops the z/TPF Internet mail server after processes that are currently running end. If you do not specify an additional parameter, all the z/TPF Internet mail servers are stopped.

ALl

starts or stops the delivery of Internet mail to other servers, and starts or stops all the z/TPF Internet mail servers.

ACcept

starts or stops the Simple Mail Transfer Protocol (SMTP) server. If you specify this parameter with the START parameter, the SMTP server will accept and deliver new mail. If you specify this parameter with the STOP parameter, the SMTP server will no longer accept new mail. Existing mail will be delivered. If you want to stop the delivery of mail, you must specify the STOP and DELIVER parameters.

Deliver

starts or stops the delivery of Internet mail to other servers and local users. If you specify this parameter with the START parameter, the SMTP server will start delivering mail. If you specify this parameter with the STOP parameter, the SMTP server will no longer accept or deliver mail.

Read

starts or stops the Internet Message Access Protocol (IMAP) and Post Office Protocol (POP) servers. The IMAP and POP servers allow you to read Internet mail.

Flush

erases the contents of the z/TPF Internet mail server queue; that is, any mail that is waiting to be delivered is removed.

STATus

displays the status of the z/TPF Internet mail servers.

SYSlog

enables or disables syslog daemon logging for the z/TPF Internet mail servers, where:

OFF: disables logging for mail messages. This is the default setting when the z/TPF Internet mail servers are started.
ON: enables logging for mail messages.

Note:

One or more z/TPF Internet mail servers must be running before you can specify this parameter.
The syslog daemon must be configured to receive mail messages. See z/TPF Transmission Control Protocol/Internet Protocol for more information about the syslog daemon.

Additional information

Online help information is available for this command. To display the help information, enter one of the following:
- ZMAIL HELP
- ZMAIL ?
The ZMAIL command is based on the postfix command of the Secure Mailer, also known as Postfix, and on the Cyrus project.
If you must stop the Internet Daemon, enter ZMAIL STOP to stop the z/TPF Internet mail servers before you enter ZINET STOP to stop the Internet Daemon.

Examples

When you configure your z/TPF system for z/TPF Internet mail server support for the first time, you will enter a series of ZMAIL commands to do the following:

Initialize the database queue pointers.
Start the IMAP and POP servers.
Create accounts for your users.
Start all the z/TPF Internet mail servers.

The following example shows the sequence of these ZMAIL commands. In this example, ZMAIL STATUS is entered at various times to show the status of the z/TPF Internet mail servers at that time. In addition, only one mail account is created in this example.

The following example shows that delivery of mail is stopped entirely; that is, the SMTP server will no longer accept or deliver mail.

User:   zmail stop deliver

System: MAIL0001I 10.41.07 START OF RESPONSE FROM ZMAIL stop
        The DELIVER MAIL service has been stopped
        END OF DISPLAY

The following example shows that logging to the syslog daemon for the z/TPF Internet mail servers is started. Any mail messages that are generated by the z/TPF Internet mail servers after this command is entered will be logged to the syslog daemon.

User:   zmail sys on

System: MAIL0003I 09.11.03 sys COMPLETED SUCCESSFULLY. NO OUTPUT TO DISPLAY
