unrouteable mail domain "yahoo.com"

This is usually caused by a DNS server failure on your web host.  The problem should only be temporary.  If you can, you may want to send email to a test Yahoo or AOL account from your local email client (using an account on the server running ListMail) to see if mail will go through.

Can you please recommend a webhosting , where listmail works without any problems?

I recommend Host4Profit, also a business opportunity, or any host running CPanel or Ensim control panels (can be found at findmyhost.com).

Alternately, depending on the size of your list I will host you for $15/mo on one of my dedicated servers.  Please contact me via the contact form at http://contact.listmailpro.com if you would like more details.
