Company email domains on Mimecast: formats and catch-all status
5 of the 111 company domains mailfloss reports on route incoming mail through Mimecast, a security gateway that filters mail before it reaches the mailbox provider, going by each domain's MX record as last observed. 0 of them mostly accept mail for addresses that do not exist. Formats and verification results are from the 90 days to November 6, 2026, or a domain's last report with enough data, dated on its page; catch-all status carries its own date.
