It's impossible to do SMTP mail exchange without MX records over the 
internet.

DNS MX records define the "Mail Exchangers" for the domain. This can 
typically mean the main SMTP in server(s) and any secondary or tertiary 
et al servers that handle mail for the domain when the main servers are 
not available. The MX records are setup in DNS with a 'waiting' to 
define if they are primary or secondary etc.

What might be an idea is to do a dump of the DNS records for your domain 
name and show your "doubting thomas" the already existing MX records 
that point to the IP of the server of your current POP host.
