It´s getting less and less common. I see plenty domains where e-mail  
spam/virus protection is outsourced and where there is absolutely no  
hope of guessing the correct hostnames for outbound or IMAP servers  
based on the domain of the MX record. Configuring Autodiscover records  
may help somewhat, but even then YMMV.
