My site is having trouble sending group emails all of a sudden.  Below is an error message that I get.  Note that there is no error description.  Line 306 is the .Send line.  Anything you can tell me would be much appreciated!

    First, I would request attention and ask for your smtp server to be removed from here.

    Next, if you are on shared hosting, check with your host what their limits are for bulk email.  They may have you throttled or blocked.  Most shared hosts do not allow sending out bulk/automated email.  Those that do, require some type of limit such as 100 per hour.  

    But from your code, it is hard to see what is happening.  I would just put in on error resume next.  Then after each send, update a table in your db with the email and time stamp it was sent. Remember this is attempted to send.  You could be throttled or blocked.  Depending on how you are blocked, you could be receiving that error.
