MDaemon responds to numerous semaphore files that can be used for a variety of useful purposes. Periodically MDaemon will scan the \APP\ subdirectory for the existence of these files. If it finds one, the associated behavior is triggered and the semaphore file is removed (only exception is locksems.sem). This provides for a simple mechanism which will allow administrators and/or developers to manipulate MDaemon without actually handling the interface.
The following is a list of all the semaphores and what they do:
ACLFIX.SEM
Runs the ACL file cleanup routine.
ADDUSER.SEM
This semaphore creates new accounts.
It is used to force MDaemon to append new records to the end of the
USERLIST.DAT file without causing a potentially time consuming complete
rebuild of the user database. Each line in this file must be a complete
account record of the form specified in the Account Management Functions
section of the MDaemon API (see MD-API.html in MDaemon's \docs\API\
subfolder). Multiple new accounts can be specified – one account record
per line. MDaemon will process the file one line at a time and add each
new account. You can create ADDUSER.LCK to lock the file while you are
updating it and MDaemon will not touch ADDUSER.SEM until ADDUSER.LCK is
deleted. To see a sample ADDUSER.SEM file open ADDUSER.SMP in your APP
directory with a text editor.
ALERT.SEM
Displays in a pop-up window the
contents of the semaphore file to all WorldClient users who are logged
in when the file is created. It is not, however, displayed to all users
immediately—it is displayed to each user individually the next time his
or her browser makes a request to the WorldClient server.
Note: Unlike other semaphore files, this file is WorldClient specific. Instead of placing it in the \app\ directory it must be placed in the \MDaemon\WorldClient\ directory.
ALIAS.SEM
Reloads aliases data file(s).
AUTORESPEXCEPT.SEM
Reloads the Autoresponder exception file(s).
BATV.SEM
Reloads Backscatter Protection (BATV) data file(s).
BAYESLEARN.SEM
This SEM manually starts the
Bayesian learning process. This is like clicking the Learn button on the
Bayesian tab of the Spam Filter. Note: this will start the Bayesian
learning procedure even if you have Bayesian learning disabled.
BESBACKUP.SEM
This SEM initiates a backup of the
BlackBerry Enterprise Server database, exactly like clicking the Backup
BlackBerry Enterprise Server database files button at: BlackBerry
Enterprise Server » Backup/Restore.
BESSLOWSYNC.SEM
Start a BlackBerry Enterprise Server (BES) slow sync operation.
BLACKLIST.SEM
Reloads the blacklist data files.
CATLIST.SEM
Reloads the internal cache of Catalog names.
CFILTER.SEM
Reloads Content Filter rules, clears Content Filter cached data, reloads the Spam Filter's White List (no filtering) file.
CLEARQUOTACOUNTS.SEM
The results of user quota
checks are maintained in the quotacounts.dat file. If you wish to clear
the cached quota value for a user, add the user’s email address to this
SEM file and then place it in the \app\ folder. If an asterisk ( * ) is
on a line by itself, the entire file will be deleted thereby
invalidating all cached quota counts.
DELUSER.SEM
You can use this semaphore file to
delete one or more user accounts. Create a text file containing the
addresses of each account that you want to be deleted (one address per
line), name the file DELUSER.SEM and then move it to MDaemon's \app\
directory. MDaemon will delete the accounts and then delete the
DELUSER.SEM file.
DNS.SEM
Reloads the Windows DNS servers and the Spam Filter's DNS settings.
DOMAINSHARING.SEM
Reloads domain sharing data file.
DYNAMICSCREENUPD.SEM
Adds entries to the
DynamicScreen.dat file. Place the desired entries into this file and
then MDaemon will manage adding them to the the DynamicScreen.dat file
in the proper manner.
EDITUSER.SEM
This semaphore is used to update
specific records within the USERLIST.DAT file without a potentially time
consuming complete rebuild. To update a specific record within
USERLIST.DAT you first construct a complete replacement record according
to the format specified in the Account Management Functions section of
the MDaemon API (see MD-API.html in MDaemon's \docs\API\ subfolder). The
new record will reflect the changes that need to be updated within
USERLIST.DAT. How does MDaemon know which record in USERLIST.DAT to
update? This is accomplished by prepending the new record with the
original record's email address followed by a comma. The EDITUSER.SEM
file can contain multiple records to update – each on its own line.
MDaemon will process the file one line at a time. You can create
EDITUSER.LCK to lock the file while you are updating it and MDaemon will
not touch EDITUSER.SEM until EDITUSER.LCK is deleted. To see a sample
EDITUSER.SEM file open EDITUSER.SMP in your \APP\ directory with a text
editor.
EXITNOW.SEM
Shuts down MDaemon.
GATEWAYS.SEM
For optimal performance, MDaemon
keeps its list of gateways in memory. Create a GATEWAYS.SEM in MDaemon's
APP directory for it to reload the gateways.dat file.
GREYLIST.SEM
Reloads Greylisting data file(s).
GROUPS.SEM
Reloads account grouping data file(s).
GRPLIST.SEM
Reloads the internal cache of Mailing List names.
HANGUPG.SEM
Forces a conditional hang-up of RAS
device. MDaemon will wait for any pending mail sessions to close and
will then hang-up the RAS session.
HANGUPR.SEM
Forces unconditional hang-up of RAS
device. This is an immediate and unconditional hang-up without regard to
mail sessions which may be in progress across the connection.
HOSTSCREEN.SEM
Reloads Host Screen data file(s).
IPSCREEN.SEM
Reloads IP Screen data file(s).
IPSHIELD.SEM
The IPShield.dat file is cached in memory to increase access speed. Use IPSHIELD.SEM to reload the file into memory
LDAPCACHE.SEM
Reloads LDAP and gateway user data file(s).
LOCKSEMS.SEM
Prevents all semaphore file processing until user removes it.
LOGSETTINGS.SEM
Reloads log file settings.
MDSPAMD.SEM
Reloads the Spam Filter white list and MDSPAMD, which forces it to reinitialize all its configuration data.
MINGER.SEM
Stops and then restarts the Minger server.
MXCACHE.SEM
Reloads MX Cache data file(s).
NODNSBL.SEM
Reloads DNSBL white list file.
NOPRIORITY.SEM
Forces MDaemon to reload the NoPriority.dat file.
ONLINE.SEM
MDaemon will create this semaphore
file once it makes a successful connection using RAS to the ISP. MD will
remove the semaphore once the connection has been terminated. This is
useful if you want to know when MD is using the RAS sub-system.
POSTDIAL.SEM
MDaemon will create this file immediately after a connection made by MDaemon is taken down.
PREDIAL.SEM
MDaemon will create this file just
before trying to use RAS/DUN. This will allow other software to detect
when it should free the dialup port so that MDaemon can use it.
PRIORITY.SEM
Reloads Priority mail data file(s).
PROCBAD.SEM
Initiates delivery of Bad Queue content.
PROCDIG.SEM
Initiates construction and delivery of mailing list digests.
PROCHOLDING.SEM
Initiates delivery of Holding Queue content.
PROCNOW.SEM
Initiates a check for remote mail and delivery of queued remote mail.
PROCREM.SEM
MDaemon will immediately go into mail processing mode and transact all remote mail.
PROCRETR.SEM
Initiates delivery of Retry Queue content.
PRUNE.SEM
Reloads auto-pruning settings.
PUBLICSUFFIX.SEM
Reloads the Public Suffix file.
QUEUE.SEM
This semaphore file is used to
enable/disable the mail queues. The file can contain any number of lines
but each one has to contain one of the following strings (one per
line): ENABLE INBOUND, ENABLE REMOTE, ENABLE LOCAL, or DISABLE INBOUND,
DISABLE REMOTE, DISABLE LOCAL.
QUEUERUN.SEM
Just before a mail session begins
MDaemon will create this semaphore file. Inside the file will be a
datestamp indicating the time and date of the most recent mail
processing interval.
RESTART.SEM
Stops and then starts MDaemon.
RESTARTCF.SEM
Stops and restarts CFEngine.exe (the Content Filter executable).
RESTARTWC.SEM

RELOADCACHE.SEM
Reloads all cached data settings and files except for Content Filter settings and files.
REVERSEEXCEPT.SEM
Reloads reverse lookups exception file.
SCHEDULE.SEM
Reloads schedule data file(s).
SPAMHONEYPOTS.SEM
Reloads spam honeypots data files(s)
SPF.SEM
Reloads SPF, DKIM, and VBR data files(s).
SUPPRESS.SEM
Reloads black list settings and clears cached domain settings.
TARPIT.SEM
Reloads tarpit and dynamic screening data file(s).
TRANSLAT.SEM
Reloads the header translation data files.
TRAY.SEM
Redraws MDaemon's icon in the system tray.

USERLIST.SEM
Reload the USERLIST.DAT file. Use this when you make modifications to the USERLIST.DAT and need MDaemon to reload it.
WATCHDOG.SEM
MDaemon will check for and remove
this semaphore from the APP directory at approximately 10-20 second
intervals. This file can be used by external apps to check if MDaemon is
running. If this file remains in the APP directory for more than 20
seconds, that is a good indication that MDaemon is no longer running.
