Hello every one, I switched to DigitalOcean from Hostgator today, but my problem is my website have alot email accounts and data from old hosting, I have alot of important emails. But when I pointed my domain to new ip adrress (DO), I can't send or get email. How can I configurate Mx record to use old "HG" Email server but my website still use DO.

for exam : mydomain.

IMAP : imap.mydomain
SMTP : smtp.mydomain.

Thanks
