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 MX record with the lower priority number (0 in this case) is the first to be tried for email delivery. If this server is unable to handle the mail request, the next lowest priority number is used, which in this case would be 10. Some email providers have only one MX record and some have well over two.
