Why McAfee MxLogic appears in this category
McAfee MxLogic — legacy hosted email security.
We classify it as a email security gateway from include: mechanisms in the SPF record matching a maintained provider rule. This is infrastructure attribution from public DNS, not evidence of a direct contract or exclusive use.
McAfee MxLogic is an email security and management platform operated by McAfee that helps organisations handle inbound and outbound email filtering, authentication, and delivery. It functions as an intermediary in email infrastructure, typically deployed by mid-market and smaller businesses as an additional layer between their mail servers and external senders.
In the wild, MxLogic appears most frequently on smaller and mid-market websites rather than on the largest global brands, with a notable concentration in the .com namespace. Its most common pairing is alongside Microsoft 365 tenants, suggesting it appeals to organisations running Exchange Online who want enhanced security filtering or compliance features. This pattern means senders may encounter MxLogic when delivering to smaller business domains, particularly when those organisations already operate Microsoft 365.

SPF authorisation and mail routing implications
MxLogic is primarily detected in email infrastructure surveys through SPF include mechanisms, meaning many organisations explicitly authorise its servers to send mail on their behalf. When a domain includes MxLogic in its SPF record, it signals that mail handling is routed through McAfee's infrastructure. For senders and mailbox providers alike, this visibility tells you that authentication checks may involve validating against MxLogic's IP ranges and that any delivery reputation affecting that domain may be tied to how MxLogic manages both inbound filtering and outbound relay.
