How to stop sending failue notice "MAILER-DAEMON' Plesk 10.4.4

[bbrian017]

Hi guys,

I've been ruining a blog community over the past 5 years. I just moved to my own dedicated server and Plesk/Q-Mail is sending me 1200 "MAILER-DAEMON' "failure notice" when I send a mass announcement. So I assume from the 10,000 members 1200 no longer have active e-mails which makes sense in my opinion.

What I would like to know is how do I disable or How to stop sending failure notice "MAILER-DAEMON'. I know I had this option last time I'm just not sure or remember how to do it.

Any help would be appreciated,

Thanks,

Brian
