- smtp <subcommand>
-
-
- These commands are used for the Simple Message Transport
- Protocol service (that is, mail).
-
- smtp batch [yes | no]
-
- If set smtp will batch the commands into one frame. When off
- only one command is sent and a response is waited for. Some old
- and flaky smtp servers cannot handle more than one command at a
- time. NOS can handle multiple. If you are not hindered by an
- old smtp server, setting batch reduces bandwidth.
-
-
- smtp bidcheck [ON | off]
-
- Sets or displays status of smtp bidchecking. Default is ON.
- If ON, incoming messages with dupe bids are rejected, with an
- error message being sent to the sender.
- NOTE: this command was deleted in Jnos 1.10K, as duplicates are
- now merely ignored, and never returned to sender.
-
-
- smtp dtimeout [<hours>] Default: 0
- Displays or sets the number of hours a message will remain in
- the smtp mqueue before being returned to sender. Delivery attempts
- are made at "smtp timer" intervals. If <hours> is zero, the message
- remains in mqueue indefinitely.
-
-
- smtp gateway [<hostid> | none]
-
- Displays or sets the host to be used as a "smart" mail relay.
- Any mail sent to a host not in the domain.txt file or not found
- via a nameserver query, will instead be sent to the gateway for
- forwarding (if defined). To undefine the gateway, specify "none".
-
-
- smtp kick [<hostname>]
-
- Run through the outgoing mail queue and attempt to deliver any
- pending mail to all systems, or just to <hostname> if specified.
- This command allows the user to "kick" the mail system manually.
- Normally, this command is periodically invoked by a timer whenever
- NOS is running.
-
-
- smtp kill [<jobid>]
-
- Kill <jobid> and delete the message.
-
-
- smtp list
-
- List the current jobs. An "L" means locked and in progress. It
- is wise to add in autoexec.bat a "del /spool/mqueue/*.lck"
- command. As of JNOS 1.10 (x16), all '.lck' files are
- automatically deleted on startup.
-
-
- smtp maxclients [<count>]
-
- Displays or sets the maximum number of simultaneous outgoing
- SMTP sessions that will be allowed. The default is 10. Reduce
- <count> if network congestion is a problem.
-
-
- smtp maxservers [<count>]
-
- Displays or sets the maximum number of simultaneous incoming
- SMTP sessions that will be allowed. The default is 0, ie, no
- limit other than the amount of memory available.
-
-
- smtp mode [queue | ROUTE]
-
- Sets the smtp delivery mode. If 'queue', all messages are left
- in /spool/rqueue for external forwarding and handling. If
- 'route', messages are handled and, if for local, appended to a
- mailbox, or if remote they are forwarded. Default = 'route'
-
-
- smtp quiet [YES | no]
-
- Enables or disables the inclusion of a beep in the message that
- new mail arrived at this system. See 'smtp trace' below, to
- enable the printing of a new-mail-arrived message.
-
-
- smtp t4 [<seconds>]
-
- Displays or sets a t4 timer for smtp client (outgoing) sessions
- so that they will disconnect after a period of inactivity and
- prevent lockups. Default = 0, i.e., no disconnect timeout.
-
-
- smtp tdisc [<seconds>]
-
- Displays or sets a disconect timer for smtp server (incoming)
- sessions so that they will disconnect after a period of inactivity
- and prevent lockups. Default = 0, i.e., no disconnect timeout.
-
-
- smtp timer [<seconds>]
-
- Displays or sets the interval, between scans of the outbound mail
- queue. For example, smtp timer 600 will cause the system to
- check for outgoing mail every 10 minutes and attempt to deliver
- anything it finds, subject of course to the smtp maxclients
- limit. Setting a value of zero disables queue scanning
- altogether. This value is recommended for standalone IP
- gateways that never handle mail, since it saves wear and tear on
- the (floppy) disk drive. Default = 0
-
-
- smtp trace [<value>]
-
- Displays or sets the trace flag in the SMTP client, allowing you
- to watch SMTP's conversations as it delivers mail. Zero (the
- default) disables tracing. A trace value of 1 just enables the
- "new mail for n5knx from <k5arh@w5ddl.ampr.org>". Larger values
- produce more voluminous trace output.
-
-
- smtp usemx [yes | NO]
-
- Displays or sets a flag enabling or disabling MX record lookups.
- This can be enabled if a domain server is available in the near
- distance (reachable). It should be disabled (default) if no
- domain server is in reach to satisfy the MX query. Note that
- MX record handling is limited to the five highest-preference hosts.
- Also, the smtp t4 timer must be set, in order to timeout on non-
- responsive hosts.
