turning off mail queue messages

Does anyone know how to turn off this email notification? If not, is there a mail queue area in iworx to where you can view mails that are stuck?

Hi. This is the qmail-send program at chat.domain.com.
I tried to deliver a bounce message to this address, but the bounce bounced!

Unable to chdir to maildir. (#4.2.1)
I’m not going to try again; this message has been in the queue too long.

NodeWorx > System Services > Mail Server > Mail Queue :wink:

(It’s the Mail Queue, by the way :D)

Thank you!
