Integralis.com doesn't matter, but _host_.integralis.com does -- does _host_.integralis.com accept connections on port 25? If so, IMHO you're the one violating the protocol -- RFC[2]821 explicitly allows fallback to A RRs in the complete absence of MX records. If that host does _not_ accept connection on port 25, you get to throw it back in their face. :) -- Greg White
