Our email server is reporting it can't send email to several domains that reside on 208.91.197.241. That IP address is associated with 208.91.196.0/23, which is Confluence Networks, which appears to be based in the BVI. A traceroute shows it stopping in Houston with Cogent. Is there an issue with connectivity to the BVI?
