Popper command - administering received mail
If the receiver MUA does not have direct access to the mail spool file, use Popper to access the mail spool on the local host. z/OS® Popper is used when a POP3 server is needed.

Parameters
The following command-line options can be used when you are invoking Popper.
- -b <directory name>
- Specifies the name of the directory in which bulletins are found.
If not specified, /usr/mail/bulletins is used
as the default.Restrictions:
- If the bulletins file is a symbolic link, it must have an owning UID or GID that matches the EUID or EGID that is assigned to Popper.
- If the bulletins file is a hard link or the target of a hard link, users that are outside the owner or group of the directory in which the bulletins file is stored cannot have write access to the directory.
- -d
- Requests more debugging messages be turned on.
- -n <message count>
- Specifies the number of old bulletins to be delivered to new users. If not specified, no bulletins are delivered.
- -s
- Requests statistics logging be turned on.
- -t <file name>
- Specifies a trace file for all message logging. If not specified, messages are logged via the syslog facility.
- -T <timeout>
- Specifies the time, in seconds, before an idle POP3 connection is terminated. RFC 1939 specifies a minimum timeout of 600 seconds, but in practice such a long timeout does not work well. (When a connection gets aborted, the user is locked out of their mailbox for the timeout period.) If not specified, 120 seconds is used as the default timeout period.
- -u
- Requests that the user mailbox be updated on abort. RFC 1939 specifies that mailboxes should not be updated (that is, no messages should be deleted) if a connection is aborted abnormally. This option forces an update to occur despite the aborted connection. If not specified, no update occurs on aborted connections.
