# smmapd(8)

Sendmail socket map daemon

 \*

## NAME

SMMAPD - Sendmail socket map daemon

## SYNOPSIS

**smmapd** \[ **-C** *config-file* \] \[ **-U** *uses* \] \[ **-T** *timeout* \]\
\
        \[ **-D** \]

## DESCRIPTION

**SMMAPD** is a Sendmail socket map daemon which is used to verify that a Cyrus mailbox exists, that it is postable and it is under quota. It accepts commands on its standard input and responds on its standard output. It MUST be invoked by [*cyrmaster*(8)](/cyrmaster/8.md) with those descriptors attached to a remote client connection.

**SMMAPD** reads its configuration options out of the [*imapd.conf*(5)](/imapd.conf/5.md) file unless specified otherwise by **-C**.

## OPTIONS

- **-C** *config-file*

  Read configuration options from *config-file*.

- **-U** *uses*

  The maximum number of times that the process should be used for new connections before shutting down.  The default is 250.

- **-T** *timeout*

  The number of seconds that the process will wait for a new connection before shutting down.  Note that a value of 0 (zero) will disable the timeout.  The default is 60.

- **-D**

  Run external debugger specified in debug\_command.

## FILES
