bell.ca is the corporate email server for their staff/execx, not given

other retail brands.

Those are the servers that you may SEND to. But it does not mean that
those are the only servers you can receive from when someone at IBM
sends you mail. Many large shops have separate SMTP servers for incoming
and outgoing mail.

MX records are only for incoming mail (you sending to them).
