I'm thinking that what this says is that it will take up to 7 days for the records to expire. It appears that their hosting company is reselling Network Solutions' DNS hosting service, but their own servers claim that they are responsible:
nameserver = ns2.mhhosting.net. mailaddress = [EMAIL PROTECTED] serial = 2002101014, refresh = 10800, retry = 3600, expire = 604800, minimum = 86400.
This is messed up enough that I'm going to tell the client to point everything at my server. I've already been through two different issues with their hosting provider last week and this seems too funky to want to deal with any more.

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?
It all depends on what the old TTLs were -- for example, I've seen people accidentally put in a very high TTL of weeks/months/years. If that happens, even if the problem is discovered quickly, any DNS server that cached any records will keep them for that high TTL.
If the records are cached for longer than that, it is not RFC-compliant, and is most likely spam that is being sent to the old IP.
