Another problem with Spamarrest and similar "services" is that some of us refuse to deal with the BS.  Oftentimes I will respond with an answer to a question to help a poster in a group and am greeted by a confirmation email from such a "service". At that point, the domain (often Spamarrest) gets reported for spam to Gmail. I'm not going through extra steps when I'm already going out of my way to help someone.

I'm sure there are others who feel the same as I do about this.  I can't tell you how many times I've had people opt-in to a mailing list and at the next distribution I receive a BS confirmation email.  Those folks get immediately unsubscribed.

So, use one of those "services" if you wish, but realize it isn't perfect.

I don't do anything in particular to control/hide my email address, other than to use different email addresses for different situations.  At least I can often tell who is selling my email address. The other thing I do is make regular reports to the FTC of emails I have received in violation of the CanSpam act....I doubt it does any good, other than give me a warm fuzzy feeling.  In any event, I find the amount of spam I receive to be quite manageable.
