Compose Mail

If I have multiple email ids against a name in contact list, I see only one email id as a drop down option, when I type the name as a recipient in compose window of zoho mail.

I, also, see that the email ids are shown if I type the First Name only.

I expect to all the email ids, instead of just one email id, if I type the First Name or Middle Name or Last Name or Nick name.
