That's not possible under the client's current setup.  I can remove the mail.domain.tld address in this case, however for clients that have SMTP AUTH and remote users, a change of this sort, or a change of the sub-domain would cause them to have to change their mail client configurations, and I would prefer to not do that for obvious reasons.

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

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
