Sendmail socket map daemon


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


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 master(8) with those descriptors attached to a remote client connection.

smmapd reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.


-C config-file

Use the specified configuration file config-file rather than the default imapd.conf(5).

-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.


Run external debugger specified in debug_command.


smmapd is commonly included in the SERVICES section of cyrus.conf(5) like so:

    imap        cmd="imapd -U 30" listen="imap" prefork=0
    imaps       cmd="imapd -s -U 30" listen="imaps" prefork=0 maxchild=100
    lmtpunix    cmd="lmtpd" listen="/var/run/cyrus/socket/lmtp" prefork=0 maxchild=20
    smmap       cmd="smmapd" listen="/var/run/cyrus/socket/smmap" prefork=0
    sieve       cmd="timsieved" listen="sieve" prefork=0
