Mail::Toaster:::Qmail - Common Qmail functions
Mail::Toaster::Qmail is a module of Mail::Toaster. It contains features for use with qmail, like starting and stopping the deamons, installing qmail, checking the contents of config files, etc.
See http://www.tnpi.biz/internet/mail/toaster for details.
This module has all sorts of goodies, the most useful of which are the build_????_run modules which build your qmail control files for you.
To use any of the methods following, you need to create a qmail object:
use Mail::Toaster::Qmail; my $qmail = Mail::Toaster::Qmail->new();
$qmail->build_pop3_run($conf, $file, $debug) ? print "success" : print "failed";
Generate a supervise run file for qmail-pop3d. $file is the location of the file it's going to generate. $conf is a list of configuration variables pulled from a config file (see $utility->parse_config). I typically use it like this:
my $file = "/tmp/toaster-watcher-pop3-runfile"; if ( $qmail->build_pop3_run($conf, $file ) ) { $qmail->install_supervise_run( {file=>$file, service=>"pop3"}, $conf); };
If it succeeds in building the file, it will install it. You should restart the service after installing a new run file.
$qmail->build_send_run($conf, $file, $debug) ? print "success";
build_send_run generates a supervise run file for qmail-send. $file is the location of the file it's going to generate. $conf is a list of configuration variables pulled from toaster-watcher.conf. I typically use it like this:
my $file = "/tmp/toaster-watcher-send-runfile"; if ( $qmail->build_send_run($conf, $file ) ) { $qmail->install_supervise_run( {file=>$file, service=>"send"}, $conf); $qmail->restart($conf, $debug); };
If it succeeds in building the file, it will install it. You can optionally restart qmail after installing a new run file.
if ( $qmail->build_smtp_run($conf, $file, $debug) ) { print "success" };
Generate a supervise run file for qmail-smtpd. $file is the location of the file it's going to generate. $conf is a list of configuration variables pulled from a config file (see ParseConfigfile). I typically use it like this:
my $file = "/tmp/toaster-watcher-smtpd-runfile"; if ( $qmail->build_smtp_run($conf, $file ) ) { $qmail->install_supervise_run( {file=>$file, service=>"smtp"}, $conf); };
If it succeeds in building the file, it will install it. You can optionally restart the service after installing a new run file.
if ( $qmail->build_submit_run($conf, $file, $debug) ) { print "success"};
Generate a supervise run file for qmail-smtpd running on submit. $file is the location of the file it's going to generate. $conf is a list of configuration variables pulled from a config file (see ParseConfigfile). I typically use it like this:
my $file = "/tmp/toaster-watcher-smtpd-runfile"; if ( $qmail->build_submit_run($conf, $file ) ) { $qmail->install_supervise_run( {file=>$file, service=>"submit"}, $conf); };
Verify the existence of the qmail control directory (typically /var/qmail/control).
$qmail->check_rcpthosts($qmaildir);
Checks the control/rcpthosts file and compares it's contents to users/assign. Any zones that are in users/assign but not in control/rcpthosts or control/morercpthosts will be presented as a list and you'll be expected to add them to morercpthosts.
$qmail->config($conf);
Qmail is fantastic because it's so easy to configure. Just edit files and put the right values in them. However, many find that a problem because it's not so easy to always know the syntax for what goes in every file, and exactly where that file might be. This sub takes your values from toaster-watcher.conf and puts them where they need to be. It modifies the following files:
/var/qmail/control/concurrencyremote /var/qmail/control/me /var/qmail/control/spfbehavior /var/qmail/control/tarpitcount /var/qmail/control/tarpitdelay /var/qmail/control/sql /var/qmail/alias/.qmail-postmaster /var/qmail/alias/.qmail-root /var/qmail/alias/.qmail-mailer-daemon
You should not manually edit these files. Instead, make changes in toaster-watcher.conf and allow it to keep the updated.
$qmail->control_create($conf);
Installs the qmail control script as well as the startup (services.sh) script.
Fetch a list of domains from the qmaildir/users/assign file.
$qmail->get_domains_from_assign($assign, $debug, $match, $value); $assign is the path to the assign file. $debug is optional $match is an optional field to match (dom, uid, dir) $value is the pattern to match
returns an array
my $selected = $qmail->get_list_of_rbls($arrayref, $debug);
We get passed a configuration file (toaster-watcher.conf) and from it we extract all the RBL's the user has selected.
returns an array ref.
my $selected = $qmail->get_list_of_rwls($conf, $debug);
Here we collect a list of the RWLs from the configuration file that get's passed to us.
returns an arrayref with a list of the enabled list from your config file.
Builds qmail and installs qmail with patches (based on your settings in toaster-watcher.conf), installs the SSL certs, adjusts the permissions of several files that need it.
$qmail->install_qmail($conf, $package, $debug);
$conf is a hash of values from toaster-watcher.conf
$package is the name of the program. It defaults to "qmail-1.03"
Patch info is here: http://www.tnpi.biz/internet/mail/toaster/patches/
$qmail->install_qmail_control_files($conf, $debug);
$conf is a hashref of values pulled from toaster-watcher.conf.
Generates the qmail/supervise/*/run files based on your settings.
Installs a new supervise/run file for a supervised service. It first builds a new file, then compares it to the existing one and installs the new file if it's changed. It optionally notifies the admin.
my $file = "/tmp/toaster-watcher-smtpd-runfile"; if ( $qmail->build_smtp_run($conf, $file, $debug ) ) { $qmail->install_supervise_run( {file=>$file, service=>"smtp"}, $debug); };
Input is a hashref with these values:
file - new file that was created (typically /tmp/something) service - one of (smtp, send, pop3, submit)
returns 1 on success, 0 on error
$qmail->install_qmail_control_log_files($conf, $progs, $debug);
$conf is a hash of values. See $utility->parse_config or toaster-watcher.conf for config values.
Installs the files the control your supervised processes logging. Typically this consists of qmail-smtpd, qmail-send, and qmail-pop3d. The generated files are:
qmail_supervise/pop3/log/run qmail_supervise/smtp/log/run qmail_supervise/send/log/run qmail_supervise/submit/log/run
Builds net-qmail with patches (based on your settings in toaster-watcher.conf), installs the SSL certs, adjusts the permissions of several files that need it.
$qmail->netqmail($conf, $package);
Builds and installs a pristine net-qmail. This is necessary to resolve a chicken and egg problem. You can't apply the toaster patches (specifically chkuser) against NetQmail until vpopmail is installed, and you can't install vpopmail without qmail being installed. After installing this, and then vpopmail, you can rebuild NetQmail with the toaster patches.
$qmail->netqmail_virgin($conf, $package);
$conf is a hash of values from toaster-watcher.conf used to determine how to configure qmail.
queue_process - Tell qmail to process the queue immediately
$qmail->restart()
Use to restart the qmail-send process. It will send qmail-send the TERM signal and then return.
$qmail->send_start() - Start up the qmail-send process.
After starting up qmail-send, we verify that it's running before returning.
$qmail->send_stop()
Use send_stop to quit the qmail-send process. It will send qmail-send the TERM signal and then wait until it's shut down before returning. If qmail-send fails to shut down within 100 seconds, then we force kill it, causing it to abort any outbound SMTP sessions that are active. This is safe, as qmail will attempt to deliver them again, and again until it succeeds.
This is necessary because things such as service directories are now in /var/service by default but older versions of my toaster installed them in /service. This will detect and adjust for that.
$qmail->service_dir_get($conf, $prot);
$prot is the protocol (smtp, pop3, submit, send).
returned is the directory
my $dir = $qmail->supervise_dir_get($conf, "smtp", $debug);
This sub just sets the supervise directory used by the various qmail services (qmail-smtpd, qmail-send, qmail-pop3d, qmail-submit). It sets the values according to your preferences in toaster-watcher.conf. If any settings are missing from the config, it chooses reasonable defaults.
This is used primarily to allow you to set your mail system up in ways that are a different than mine, like a LWQ install.
$qmail->smtpd_restart($conf, "smtp", $debug)
Use smtpd_restart to restart the qmail-smtpd process. It will send qmail-smtpd the TERM signal causing it to exit. It will restart immediately because it's supervised.
my $available = $qmail->test_each_rbl($selected, $debug);
We get a list of RBL's in an arrayref and we run some tests on them to determine if they are working correctly.
returns a list of the correctly functioning RBLs.
Runs the following tests:
make sure qmail_dir exists make sure vpopmail home dir exists make sure qmail_supervise is not a directory
