Are, by chance the emails that are getting misdirected coming from
folks that are also customers of the old hosting company?
I noted this effect when I switched hosts. The reason it happens is
that from the same server/provider, the mail server thinks the DNS
records at the old company are authoritative because the mail server
doesn't go out to the internet to check otherwise.
The only fix is to have the domain purged from the old company's DNS
records. That way, when the old company mail server goes to deliver
@yourdomain.com the resolver will have to go to the root servers and
they'll point it to the right DNS records, correct new IP and send
your mail to the right place.
