The Synology MailPlus allows you to set up a secure, reliable and private mail server directly on your Synology NAS. Some may ask why set up your own mail server when there is Google Apps for Work? Some of the reasons that I could think of are:
- Small email volume and hence do not need a hosted email service;
- Your environment only require email correspondence between colleagues and strictly off the Internet (e.g. research & development) for confidentiality reasons;
- You don’t wish to have an elaborated set up (Microsoft Exchange, Active Directory, etc.) for SOHO and/or small businesses.
Whatever your reason may be, if you are looking for a quick and secure private mail server set up. Do read on to find out what MailPlus Server has to offer.
The Synology MailPlus feature has got two main components:
- MailPlus Server. This is essentially the heart of your email message sending and receiving; and
- MailPlus Client. Synology provides a web client for you to check, compose and send email messages from a web browser. For Android and iOS, there is also the MailPlus client on the respective application store. Lastly, you can also use your favorite mail client on operating systems like Microsoft Windows, OS X, Linux, etc.
Some Primer on Mail Server
If you are intending to host your own email server to send and receive emails over the Internet, do be informed that your Internet Service Provider (ISP) has to permit the respective SMTP, POP3 and IMAP ports. Some ISPs have blocked these ports to mitigate email spams.
If you are unaware, SMTP server, if not configured properly (i.e. not requiring SMTP authentication), allows malicious users/spammers to send spam mails.
