Question Mails delivered after i uninstalled the product

Hi,
I was testing out vbmail lite version.
I installed the product smoothly. Then i created a test mail list. I tried every possible option in the setting, SMTP, php, imap, different ports, i checked the server, then i checked if original vbulletin mail sending option is working or not. All did not work, I sent 10's of mail for an hour but none of them delivered.
Then after about an hour, as soon as i uninstalled the product, suddenly all the mail i tried to send are delivered.
Was it an awkward coincidence or are they delivered because i uninstalled the product?
Regards

I'd say that's an awkward coincidence, because mails are only queued using vBulletin's mail queue system. A cron job runs every 10 minutes and sends X number of emails in the queue.

However, if either your forum had a queue built up, or nobody triggered the cron job until an hour later, that would explain the delay

Then we can say, vbmail is working. Right?
I can reinstall it

That's correct

Tested and confirmed that, it was a coincidence. Vbmail works like charm.
