You then have a calendar or a contacts address book connection using that server, most likely.
Look through the Passwords & Accounts listings for accounts associated that server.
Also check for references in BOTH parts of each mail account, too. BOTH PARTS. Mail has TWO groups of settings, one part with settings and host server name and credentials reading and receiving, and a separate group of credentials for sending mail. CHECK BOTH.
