Scheduled Jobs for Dada Mail
Some of Dada Mail's more powerful features depend on a cronjob to be run on a periodic schedule.
Only one cronjob is required for all scheduled tasks in Dada Mail. It is composed of a URL that will need to be accessed.
Here's an exmaple:
http://example.com/cgi-bin/dada/mail.cgi is just the URL to your Dada Mail,
A full cronjob would look like this:
*/5 * * * * /usr/bin/curl --user-agent "Mozilla/5.0 (compatible;)" --silent --get --url http://example.com/cgi-bin/dada/mail.cgi/_sched513A3F128C5C41EC/_all/_all/_silent/
*/5 * * * * sets the schedule to run this job every 5 minutes,
/usr/bin/curl --user-agent "Mozilla/5.0 (compatible;)" --silent --get --url is the curl command, with different paramaters passed to grab the URL and,
is the URL we want to grab.
_sched513A3F128C5C41EC is an individual flavor for our specific install of Dada Mail. It's meant to be somewhat unique, so that someone nefarious doesn't start running all the schedules for all Dada Mail installations it can find.
This flavor can be set when installing Dada Mail via the Dada Mail Installer. It can also be set manually in your
.dada_config file, in the
SCHEDULED_JOBS_OPTIONS hashref. Look for the
If you would like to customize the Schedule Flavor, the value of this paramater should only contain letters, numbers and underscores. Anything too tricky will foil the run mode dispatch code of Dada Mail. This value should also NOT be the same as an already-existing flavor/run mode
Job To Run
The next value in the path,
_all describes which jobs to run.
_all is special: it runs all the jobs can be run.
You can also modify this to run a specific job. The following are also supported:
Checks up on the status and health of any mass mailings currently going out. This used to be the job (prior to v8) of the Mailing Monitor plugin
This job checks to see if any mass mailings that are run at a schedule time need to go out.
This job runs jobs for the Bridge plugin. This be to check for any awaiting discussion messages that are awaiting to be sent out, or if a digest message should be created and sent.
This job runs the Bounce Handler, which checks the bounce handler's email account for any awaiting bounced messages to process.
Mailing List to Run
The next value in the path,
_all (and then second
_all found) describes which list to run jobs for.
_all is specially, as it will run jobs for all the mailing lists you have. If you would like to run jobs for just one mailing list, you can change this paramater the list short name of that list.
By Default, this is set to,
_verbose which will print out the output for all the jobs run. If you would like to suppress this, you can, by setting this to,
Another option is to supress the output in the cronjob itself, like this:
*/5 * * * * /usr/bin/curl --user-agent "Mozilla/5.0 (compatible;)" --silent --get --url http://example.com/cgi-bin/dada/mail.cgi/_sched513A3F128C5C41EC/_all/_all/_verbose/ >/dev/null 2>&1
Running the scheduled jobs via the command line.
There's no special command-line way to run these jobs, although you can invoke Dada Mail on the command line easy enough. The following:
cd /home/youraccount/public_html/cgi-bin/dada; /usr/bin/perl ./mail.cgi flavor=_sched513A3F128C5C41EC schedule=_all list=_all output_mode=_verbose
Will do the same thing, as our initial example for curl.
