It looks like you are being blocked from simply sending too many emails to members in a 24 hour period, not because of the content of those e-mails.
You are limited to just a few e-mails per day to members, because more than this our system things you are a spammer trying to email too many people, which is unusual. Simply limit your e-mails to members and use the comment feature on their artwork to avoid the spam block.
I was sending a nice note to Michael Weber on the portfolio contact page Subject: My favorites.... Message: You have been working hard on your portraits, Great job. I expecialy like the Ketchup bottle still life, nicely done!
What is wrong with the spam filter?????
