I'm having an issue whereas my mail server is getting clogged with emails supposedly because qmail is trying to send too many messages at once. The emails are not spam. They are notifications sent out individually at unique times by my system to let users know they have no pm's, new comments on their blogs or password resets. Much like how a forum would work.
Each day when I look at the mail queue it keeps piling up and although some emails are being sent, the rate at which they are sending is causing me to have a customer service nightmare.
I have search for help on this matter, but alas have come up empty. Any help is greatly appreciated.
