Email Question

Hi all,

   I'm wondering if there is some sort of filtering or blocking of emails. Some family members and I are part of an email group and we are not receiving those email however other people (not subscribed using videotron email) are getting those emails. Is there some way to know if those emails are being filtered? I've checked to make sure that if not in my spam filter or filtered into a different folder in my outlook.

Any ideas?
