wpsb-opt-in sendblaster widget

trying to use sendblaster free, I installe the widget to my wordpress site.
overall, it’s working and I can get the subscribers into sendblaster.
BUT:
1. if if ask for the double opt-in option in the widget, I get a meassage from my provider FREE.FR which says SPAM mail detected, the mail was not sent. So the subscribtion desn’t work. If I remove this option, it works without confirmation process.

2. I can get the emails, but no additional fields such as name or whaterver. the tags #2# or #link# ar not translated and stay as is

3. what does it mean “limited to 100 messages per day” with the FREE edition of sendblaster ? is it possible to keep sending the rest of the mails the day after or does it mean you are really limited to 100 emails in your list?

If anyone could answer these questions, it would help me a lot
