    My Mail queue has around 850 messages. Not sure if this is allot but I do have roughly 120 sites installed on the server with one user having almost 350accts. How can figure out if these processes are outgoing or incoming emails. Also, I look in the WHM - Relayed Emails area. Nothing unusual in there. I have my mailserver to not send more than 125 emails per hour along with user nobody gets denied sending email. So i'm thinking I am getting mail bomed?

    This is usually a sign that one or more of your accounts has the default mail setting :blackhole: You need to change them all to :fail: . All those mailnulls in my experience come from the server having to process mis-addressed email instead of just bouncing them.

    I wish I could tell you an easy way finding out which accounts are set to :blackhole: but I can't. Perhaps some else here can.

    Hello all,

    I have found that there was a reseller account which had all their accounts setup with a catch=all email on everything. I went ahead and set it to discard with error to sender but after I click it all I get is: Current Setting: Updating.... that shows up in the default address screen. I've made the changes like 15mins ago and still hasn't updated the settings yet.

    Can someone advise please.

    FYI this must be a bug. IT seems if the lanugauge is set in spanish the change of the catch-all doesn't get saved. If you set it back to english it will allow you to change it to set email as fail: no such user.

    cPanel should look at this.

    in the meantime, after going through all the accounts on the server I am still getting allot of mailnull processes showiing up. Right now I have about 30 of them going. Sometimes it gets smaller sometimes it gets larger. What else could be causing this much mailnulls?

    Anyone care to help.

    I have disabled the feature in cPanel and I have personally went through over 130 accounts and made sure they are all set to "fail with bounceback" emails. I still get 50 mailnull processes going at one time.
