Which queue are the mails hanging in?

Some mail may hang in the outbound queue if the server is not working correctly at the other end. This will happen sometimes when users reply to bogus SPAM.

Where is your mail stuck?

You want to get with you internet provider and have them enter a reverse DNS entry for your domain.

Many companies these days will bounce mail if they cannot determine a reverse DNS on your mail server. That's more or less a standard now.

After that you might want to take a look at some of the mail in this queue. Where is it going to? Does it look like outbound SPAM? If so you may have an infected machine on the network that is filling the queue with garbage. If they are legitimate you can look at the destinations and perhaps talk to an admin there. Have them help you do some testing. Lastly take a look and see if your domain has been blacklisted.
