Email hosting service where you can use your own domain? - Divisions by zero

Hi everybody, I’ve had a domain name at Gandi.net [http://Gandi.net] for quite a while, which included 5 email addresses as well, hosted on my domain. Now they’re however discontinuing this offer, it will now be €3,99 per month per mailbox. So, I’ve been looking around a bit. I need a service that allows me to connect it to my own domain name, that actually allows IMAP instead of requiring a special client, and preferably should allow me to put up several mailboxes under the same account since I currently have mailboxes for some of my family members. Security is not a concern since this is only intended to be used for the email I send and receive under my actual legal name, and I know better than to use email for confidential material. Zoho Mail seems like a good deal, since they have 10GB per user for only €1,13 a month. I’m just afraid that my emails might end up in spam filters since they’re based in India.
