Is the list getting my e-mails?

[Mario Lobo]

   Hi;
   Forgive for this test.
   Recently I changed my domain to another ISP.
   Since then, I have been unable to post to the lists I'm subscribed to.
   I created a gmail account, switched to it and nothing. Now I switched
   back to mlobo at digiart.art.br and nothing.
   I can get into the management page, I marked to receive my own posts
   and nothing.
   I get all the posts to all the lists except mine.
   Am i being blocked?
   Could anyone just simply reply this post?
   Thanks,
   Mario Lobo
