Deploying mail servers
Red Hat Enterprise Linux 9
Configuring and maintaining mail server services
Abstract
On Red Hat Enterprise Linux, you can provide reliable and secure mail services for your customers and internal users by using the mail transport agent Postfix as SMTP service and the mail delivery agent Dovecot as IMAP and POP3 services. Both services integrate with each other and they support central backends, such as LDAP directories to store account data and to authenticate users.
