# smapd(8)

sendmail wrapper daemon

## NAME

smapd - sendmail wrapper daemon

## SYNOPSIS

**smapd** \[invoked from rc.local\]

## DESCRIPTION

The **smapd** daemon periodically scans the mail spool area maintained by **smap,** and delivers any messages that have been gathered and stored. Mail is delivered via **sendmail,** and the spool file is deleted. If the mail cannot be delivered normally, **smapd** can be configured to store spooled files to an area for later examination.

## OPTIONS

**smap** takes no command line options, reading its configuration information from the firewall toolkit configuration file **[netperm-table(5)](/netperm-table/5.md)** All configuration rules in **netperm-table** for application "smapd" are read, and the following clauses and parameters are recognized:

- **executable pathname**

  Specifies the pathname of the **smapd** executable itself. For historical reasons, **smapd** forks and execs copies of itself to handle delivering each individual message. **THIS ENTRY IS MANDATORY**

- **sendmail pathname**

  Specifies an alternate pathname for the sendmail executable. **Smapd** assumes the use of sendmail but does not require it. An alternate mail delivery system can replace sendmail, but it should be able to accept arguments in the form of:\
   *executable -f fromname recip1 \[recip2 ... recipN\]*\
   Since the exit code from the mailer is used to determine the status of delivery, replacements for sendmail should use similar exit codes.

- **baddir pathname**

  specifies a directory where **smapd** should move any spooled mail that cannot be delivered normally. This directory must be on the same device as the spool directory, since the [rename(2)](/rename/2.md) system call is employed. The pathname specified should not contain a trailing '/'.

- **userid name**

  specify the userid that **smapd** should run under. The name can be either a name from the password database, or a numeric user-ID. This userid should be the same as that under which **smap** runs, and should have write permission to the spool directory.

- **directory pathname**

  Specifies the spool directory in which **smapd** should search for files. **smapd** should have write permission to this directory.

- **wakeup value**

  specifies the number of seconds **smapd** should sleep between scans of the spool directory. The default is 60 seconds.

## INSTALLATION

To install **smapd,** configure the **executable** and **directory** options in **netperm-table,** and add it to **/etc/rc.local**

Sample **netperm-table** configuration for **smap** and **smapd:**

```
# email wrapper control
smap, smapd:            userid 4
smap, smapd:            directory /mail/inspool
smapd:                  executable /usr/local/etc/smapd
smap:                   maxrecip 4000
smap:                   maxbytes 1048576
smap:                   timeout 3600
```

In this example, both **smap** and **smapd** are running with user-id #4 (uucp) in the spool directory **/mail/inspool.**

Since **[sendmail(8)](/sendmail/8.md)** is not running in daemon mode, messages that cannot be delivered and are queued must be delivered by periodically invoking sendmail to process its queue. Add a line like:

0,30 \* \* \* \* /usr/lib/sendmail -q \> /dev/null 2\>&1

to the **[crontab(5)](/crontab/5.md)** file.
