A mail server is a server used to receive, send and manage e-mails. Thus a mail server is always involved as soon as you write, receive or send an e-mail.
Every provider of e-mail services operates its own mail servers, including IONOS.
Webmail from IONOS is already designed for use with our mail servers. Therefore, our customers do not have to do anything to use our mail servers.
