ISP address changes causes problems

Two weeks ago, my ISP changed its mail server IP address. We have a virtual domain in it. Since then we can't send e-mails to an specific ISP, which receives without problems from everybody, less from my virtual domain. How do I can solve this?

Check with the ISP to make sure that your MX records are set up properly. Then check your own DNS records and make sure that they reference the new IP address. You might have to flush your arp cache on the mail server or on your own individual machines.
