| 7 | SYNOPSIS |
|---|
| 8 | etrn [-v] server-host [client-hosts] |
|---|
| 9 | |
|---|
| 10 | DESCRIPTION |
|---|
| 11 | SMTP's ETRN command allows an SMTP client and server to |
|---|
| 12 | interact, giving the server an opportunity to start the pro |
|---|
| 13 | cessing of its queues for messages to go to a given host. |
|---|
| 14 | This is meant to be used in start-up conditions, as well as |
|---|
| 15 | for mail nodes that have transient connections to their ser |
|---|
| 16 | vice providers. |
|---|
| 17 | |
|---|
| 18 | The etrn utility initiates an SMTP session with the host |
|---|
| 19 | server-host and sends one or more ETRN commands as follows: |
|---|
| 20 | If no client-hosts are specified, etrn looks up every host |
|---|
| 21 | name for which sendmail(1M) accepts email and, for each |
|---|
| 22 | name, sends an ETRN command with that name as the argument. |
|---|
| 23 | If any client-hosts are specified, etrn uses each of these |
|---|
| 24 | as arguments for successive ETRN commands. |
|---|
| 25 | |
|---|
| 26 | OPTIONS |
|---|
| 27 | The following option is supported: |
|---|
| 28 | |
|---|
| 29 | -v The normal mode of operation for etrn is to do all of |
|---|
| 30 | its work silently. The -v option makes it verbose, |
|---|
| 31 | which causes etrn to display its conversations with |
|---|
| 32 | the remote SMTP server. |
|---|
| 33 | |
