12
14 smmapd is a Sendmail socket map daemon which is used to verify that a
15 Cyrus mailbox exists, that it is postable and it is under quota. It
16 accepts commands on its standard input and responds on its standard
17 output. It MUST be invoked by master(8) with those descriptors at‐
18 tached to a remote client connection.
19
20 smmapd reads its configuration options out of the imapd.conf(5) file
21 unless specified otherwise by -C.
22
24 -C config-file
25 Use the specified configuration file config-file rather than the
26 default imapd.conf(5).
27
28 -U uses
29 The maximum number of times that the process should be used for
30 new connections before shutting down. The default is 250.
31
32 -T timeout
33 The number of seconds that the process will wait for a new con‐
34 nection before shutting down. Note that a value of 0 (zero)
35 will disable the timeout. The default is 60.
36
37 -D Run external debugger specified in debug_command.
