Hey, as others have pointed out in this "tough economy" at least it's a 
job.  I'll take the congratulations but please don't tease ;)

Don't ask me. I just do the back end programming ... or more precisely 
*did* until I also got stuck with the sysadmin stuff too when the admin 
left since I was the only one who has even heard of Linux. It's been a 
great learning experience but every day is a trial by fire ... it's 
given great respect for sysadmins.

They are not supposed to. We only use the one domain name, 
tokyo-avland.co.jp, the others were taken "just in case" and point to 
tokyo-avland.co.jp.

I'm a bit lost here. Are you in my zone files I can set the MX record to 
point to my SMTP machine, even if the SMTP machine has no relationship 
whatsoever with the domains in question? (i.e. there are no accounts (if 
such a thing exists) for those domains on the SMTP server and it 
definitely is not set up for relaying).

I don't want someone thinking the MX record is valid and try sending 
email to those domains ....

Thanks,
