CBSubs mailer sending out duplicate email messages

Ive a problem with duplicate email msgs being sent in mailer and wondering if I could get some ideas as to how to track down why this is happening - joomla cb and cbsubs are up to date

There are 8 published mailers - they are all going out as duplicates

So I thought its the cron job - here it is with the domain masked

#This cron task will run the cbsubs mailer rules every 5 mins and put msgs in the outbox
*/5 * * * * wget -O - -q -t 1 " abcde.org.au/index.php?option=com_comprofiler&task=pluginclass&plugin=cbpaidsubscriptions&cbpact=cbsubsclass&cbpclass=mailer&user=62&cbpmailerdo=cronprocesssendmailqueue&key=d41d8cd98f00b204e9800998ecf8427e&format=raw "

Any ideas to resolve this greatly appreciated

cheers

That is entirely too quickly. My guess is you're causing mailer processes to overlap. Ideally you should only be processing the mailer queue once or twice a day at most. The only way it'd be ok to run it that often is if you run "Url of cron task to process mailers rules" every hour to put users into the queue then run "Url of cron task to process mailqueue" at the end of the day to process the queue, but that isn't really necessary as running "Url of cron task to both process mailer rules into queue and then to process mailqueue" (the URL you're currently using) every 24 hours should be sufficient.

Additionally you can use "Maximum messages per customer (0=unlimited)" to directly limit the number of times the mailer is sent to them. "But do not send message if it's later than" can be used to limit the date check range as well.

Thanks Krileon - no idea why I set the cron job to fire every 5 mins - a momentary lapse of reason I guess!
So Ive implemented a once a day cron process so hopefully that will resolve the duplicate messages
Just waiting for the next msg to fire and will see the outcome
