The MailPlus and MailPlus Server packages allow your business to set up a secure, reliable, and private mail server, while giving your employees a modern mail client to receive and send messages. Furthermore, MailPlus and MailPlus Server are packages that can be installed on your Synology NAS, so there’s no need to rely on third-party services. Best of all, MailPlus comes with 5 free accounts and flexible licensing plan to fit your needs.
Synology MailPlus comes with 5 free email accounts and allows you to add more accounts by purchasing additional licenses according to business needs. There are two versions of license packs available: 5 or 20 units of email accounts, both with 1-year validity, so you can use the mail service and migrate the licenses freely within one year upon license activation. In addition, email aliases are not considered to be email accounts, so no extra licenses are required.
No additional fee will be charged for the high-availability support in MailPlus. One cluster includes 5 free mail accounts by default, and additional licenses are required for the total number of enabled accounts from LDAP server or Windows AD domain. For example, if you want to enable 25 email accounts in the high-availability cluster, then 20 additional licenses are needed.
MailPlus Web Client and Mobile App
MailPlus web client and mobile app will be updated regularly and can be used for free in conjunction with MailPlus Server. However, their functions will be affected or limited if there are insufficient valid licenses in MailPlus Server. In addition, MailPlus web client and mobile app require MailPlus Server to run.
