Possibly a bad MX record in the DNS for some person you were sending mail to.  I show that ip address as beloing to www1dm.webair.com.  Its likely nothing to do with Verizon, but with that persons email provider.

Note many companies, including Verizon typically don't allow port 25 to be used anymore.
