Re: [amibroker] Another Hard Bounce

["Edward Pottasch" <empottasch@xxxxxxxxx>]

thanks. I dont't know too much about this bouncing. I only noticed it when I was not receiving my Amibroker Emails I normally send forward from Yahoo to my normal Email address. If I didn't miss these Emails I wouldn't have known. It all started when I changed my ISP but as I said it seems to stop if I change a setting in the McAfee security center.  I will look into it a bit closer,

thanks,
rgds, Ed

  Ed,

  Nobody is ever going to accuse me of being the master about this
  subject. ^_^

  But I would do the following:

  1) Get a Bayesian filtering program. (I use K-9.)

  2) Never use anything that produces bounces.

  3) Use a whitelist.

  4) Use a blacklist, too.

  Generally, my combination gets about 99.75 percent correct. Yes, I
  get some false negatives (SPAM that is not identified as SPAM). More
  rarely, the false positive (identified as SPAM that isn't).

  But all the identified-as-SPAM mail goes to the trash, where I can
  analyze it in seconds.

  "Unprotected", I don't know. But bouncing SPAM email is a no-no. You
  are bouncing messages to people that had *nothing* to do with the
  original message. Much better to silently accept, filter, and
  dispose. Never, ever, acknowledge receipt of SPAM. A bounce, should
  it even go to the true sender (highly unlikely), would do just that.
  Simply ignore. Delete and forget.

  Bayesian filters are impossible to defeat. They can be circumvented,
  temporarily, but they "learn". Every time they mess up, you teach
  them. They get "smarter".
