  The "dig" command can get them for you $ dig ycombinator.com mx ;; ANSWER SECTION: ycombinator.com. 300 IN MX 20 alt1.aspmx.l.google.com. ycombinator.com. 300 IN MX 10 aspmx.l.google.com. ycombinator.com. 300 IN MX 20 alt2.aspmx.l.google.com. ycombinator.com. 300 IN MX 30 aspmx4.googlemail.com.

    this doesnt work if they use a 3rd party email filtering service like mimecast or proofpoint fyi.

        Proofpoint, definitely a very big red flag.
