// Given a list of identities (email addresses and/or domains), returns the
// verification status and (for domain identities) the verification token for each
// identity. The verification status of an email address is "Pending" until the
// email address owner clicks the link within the verification email that Amazon
// SES sent to that address. If the email address owner clicks the link within 24
// hours, the verification status of the email address changes to "Success". If the
// link is not clicked within 24 hours, the verification status changes to
// "Failed." In that case, if you still want to verify the email address, you must
// restart the verification process from the beginning. For domain identities, the
// domain's verification status is "Pending" as Amazon SES searches for the
// required TXT record in the DNS settings of the domain. When Amazon SES detects
// the record, the domain's verification status changes to "Success". If Amazon SES
// is unable to detect the record within 72 hours, the domain's verification status
// changes to "Failed." In that case, if you still want to verify the domain, you
// must restart the verification process from the beginning. This operation is
// throttled at one request per second and can only get verification attributes for
// up to 100 identities at a time.
