Our mailer gets marked as spam every so often because some of the key words (which we try to avoid now), for example, Iron Butt is always referenced as IBA now. I'll put in the required form with Yahoo again, but this should solve it:
Send a note to
[email protected] from Yahoo (or your mailer, for example, gmail)
In the subject line, you have to put something in, Hi Mike works
and in the body of the message, something like, Hi Mike
Mike
