[Declude.JunkMail] Client receiving E-mail to non-MX address

[Matt]

I have a client that we switched over to our service last Thursday.  The 
mail server is located at mail.domain.tld (according to the A record), 
but their MX records on their authoritative DNS server both point to 
us.  Unfortunately, they are still receiving E-mail directed at their 
server instead of going through ours.

Is this a common long-term issue where some spamware will automatically 
try the mail.domain.tld address, or is it possible that this is being 
cached for this long?  I don't believe there are any issues with 
timeouts causing this E-mail to fall over to other addresses, and their 
site is on an address range that is different from their mail server.  I 
would hate to have to tell clients that they have to change the name of 
their SMTP server if it's called "mail."

Thanks,

Matt
