Non valid email retry queue

[koendendas]

Hi,

I created a PHP script which sends an email to a subscriber who entered his email address on my site.
It checks if the email address has a valid format.
Someone however entered a non existing email address.
So my mailing queue in DirecAdmin keeps trying to send an email to an address that has a valid format, but that is a non existing address.
The queue is now filled with Retries and a new one is added every 15 minutes.
Is there a way to stop this? Or is this discarded after some time?

Thanks,

Hello,

Check and tune retry section of exim.conf

The defaults are as following:

# This single retry rule applies to all domains and all errors. It specifies
# retries every 15 minutes for 2 hours, then increasing retry intervals,
# starting at 1 hour and increasing each time by a factor of 1.5, up to 16
# hours, then retries every 8 hours until 4 days have passed since the first
# failed delivery.
