it's ok, it comes with the job!!

no, the MX record is used by SMTP servers wanting to dump mail on that domain.

"Imail Web msging" is over the http protocol (not SMTP protocol) and so the 
browser will look in the DNS for mail.domain.com, ie the A record and then 
go to the ip address for the mail.domain.com and check into port 80 for 
http service (listened to by Imail web server).

so you need an MX record for domain.com and of course a A record for 
mail.domain.com.

domain.com              IN   A    ipaddress  (of standard web server)
www.domain.com  IN   A    ipaddress  (also could use CNAME RR here)
domain.com              IN   MX   5 mail.domain.com

mail.domain.com IN   A    ipaddress (of the Imail machine)

So mail gets sent to mail.domain.com,  and his web msging URL is 
mail.domain.com, but his web site is www.domain.com.

Got it?
