My server has been a target for excessive spam e-mails. I deleted few mailboxes & bounced back the spam emails to their senders, however this is triggering my hosting provider to think that I am sending out huge volume of spam. I checked the outgoing spam log, and the majority of the e-mails are being rejected due to mailbox being full. I am running CentOS with Cpanel. I need someone to somehow find a solution for this. I will need a detailed transcript as to what you plan on doing.

Stop bouncing spam mail. That creates back scatter and your server will get black listed pretty fast. Instead, stop accepting mail for non existing accounts (Reject unknown mail) and clear out those filled mail boxes.
