Accounts transferred, email problems :S

[ukgaz]

Hi,

I tranferred all my accounts from my old cpanel server to my new one,

Updated the DNS records with my registrar to the new ips, unfortunately e-mail is not working, i used the trouble shooter and seems to trying to relay or something my mail to the old IP.
any suggestions,

I keep getting this error when trying to send to an account

IPdoes not like recipient.
Remote host said: [IP DOMAIN] is currently not
550-permitted to relay through this server. Perhaps you have not logged into
550-the pop/imap server in the last 30 minutes or do not have SMTP
550 Authentication turned on in your email client.
Giving up on [IP].

fixed, /etc/localdomains didn't update

Same problem here. Is there a way to ensure that the localdomains file will update on transfer. Looks like it happens with some of the parked domains.
