Aventis CropScience submitted this letter, along with an executive summary, in an effort to demonstrate that StarLink corn should be granted a time-limited food tolerance exemption by the Environmental Protection Agency, which would limit the potential disruption to the food chain from any StarLink corn prior to the voluntary withdrawal of the StarLink registration.
MX record. A mail exchanger record (MX record) is a type of resource record in the Domain Name System that specifies a mail server responsible for accepting email messages on behalf of a recipient's domain, and a preference value used to prioritize mail delivery if multiple mail servers are available.
* The TTL is the number of seconds before subsequent changes to the MX record go into effect. Once the MX records are configured correctly, we recommend changing the TTL value from 3600 to 86400, which tells servers across the Internet to check every 24 hours for updates to the MX record instead of every hour.
