That could possibly be the reason; but as I've investigated your account, I've found out that it was blocked by our automated spam filters. I've now unblocked your account so that you can send messages again. You may try it out.
Here are some tips to prevent this thing from happening again:
• Check your contacts and recipients lists to make sure that only people who want to receive the messages will receive your messages.
• Reduce the number of messages that you send to large groups of people so that they are less likely to think your messages are unwanted mail.
• Limit the number of chain letters, e-mail jokes and other messages that you send to help people recognize your mail as wanted and to make it more likely that your message will be allowed past your recipients' junk mail filters.
• Check all the contacts in your address book to make sure that the accounts are still active.
