# extsmaild(1)

robust sending of e-mail to external commands

## NAME

**extsmaild** – robust sending of e-mail to external commands

## SYNOPSIS

**extsmaild** \[**-m** *mode*\] \[**-t**\] \[**-v**\]

## DESCRIPTION

**extsmaild** sends messages spooled by [extsmail(1)](/extsmail/1.md). If called without  **-m** specified, or if **-m** *batch* is specified, **extsmaild** operates in batch mode, running as a foreground process and terminating after trying to send all messages; it returns 0 if all messages were sent successfully, or 1 if any messages remain unsent.

If called with the **-m** *daemon* switch, **extsmaild** operates as a long running daemon; it monitors the spool directory and when it notices changes to the directory (or a fixed period has elapsed) it tries to send any unsent messages. This means that even on unreliable networks, **extsmaild** can easily be left alone and relied upon to ultimately send all messages - without manual intervention.

The **-t** flag can be specified to test the configuration files for **extsmaild** without running the mail sending process.

The **-v** flag prints version info to stdout, then exits.
