I want IMAP access to multiple email IDs

I want IMAP access to multiple email IDs

I have made two email IDs from my hosting provider's cPanel. But I don't have any knowledge regarding MX records, etc. So I don't know what to point where. One is personal, name@company.org and another is for other members, control@company.org

I want both these emails to be available through email clients like Thunderbird. Please advice:

What to change in MX records; and how to set up the account.
