System Administration Commands etrn(1M)

|
||
NAME
|
||
etrn - start mail queue run
|
||
|
||
SYNOPSIS
|
||
etrn [-v] server-host [client-hosts]
|
||
|
||
DESCRIPTION
|
||
SMTP's ETRN command allows an SMTP client and server to
|
||
interact, giving the server an opportunity to start the pro
|
||
cessing of its queues for messages to go to a given host.
|
||
This is meant to be used in start-up conditions, as well as
|
||
for mail nodes that have transient connections to their ser
|
||
vice providers.
|
||
|
||
The etrn utility initiates an SMTP session with the host
|
||
server-host and sends one or more ETRN commands as follows:
|
||
If no client-hosts are specified, etrn looks up every host
|
||
name for which sendmail(1M) accepts email and, for each
|
||
name, sends an ETRN command with that name as the argument.
|
||
If any client-hosts are specified, etrn uses each of these
|
||
as arguments for successive ETRN commands.
|
||
|
||
OPTIONS
|
||
The following option is supported:
|
||
|
||
-v The normal mode of operation for etrn is to do all of
|
||
its work silently. The -v option makes it verbose,
|
||
which causes etrn to display its conversations with
|
||
the remote SMTP server.
|
||
|
||
ENVIRONMENT
|
||
No environment variables are used.
|
||
