  • Qmail - Email Scanner Add-on

    I wanted to know if there are any good email scanners (I found this one http://qmail-scanner.sourceforge.net/). I know there are lots of uses for scanners, but I wanted to see if I could get an automated email service going.

    Basically to have a list of newsletter emails in a database table. You send out emails and with qmail scanning all incoming emails it can see if an email comes in (to a particular email, in this case the FROM email on the newsletter email) then it can scan it and check for an error in the Subject / Body of the email. Based on the scan if it meets a search criteria it can remove the email from the database by running a program, shell script, PHP script, etc. This would make it much easier to maintain a valid list of emails. Also, could be use as another option for users to Opt-out instead of just using a web based form they could send an email to removeme@domain.com with the subject as remove.

    Example Email Returned by AOL:
    From: Mail Delivery Subsystem <MAILER-DAEMON@aol.com>
    To: "THE FROM EMAIL"
    Subject:Returned mail: User unknown
