Best webmail client and protocol to use?

Linode Staff


I would like your advice on setting up a mail server in my Linode. I've read through this web page:

And got very useful information. However, I am new to such topic and not sure which MTA, MDA, IMAP (I guess I won't use POP3) and Webmail client I should choose, based on the capacity of my Linode, and security concern. The Spam and Virus protection would be my biggest concern, because I totally have no experience on this.

Thank you for your help!

Hey there,

We're excited to hear about your jump into mail servers! As with most things on Linux, there are a lot of options available to you. The best fit is going to depend on your goals and your current stack.

A Linode staff member shares a number of solutions with step-by-step instructions in another community post for you to review here.

I also recommend that you familiarize yourself with basic server security and hostnames, as this will further protect your mail client.

Thank you for redirecting me to the detail instructions. I could not post a note under that link , that's why I have to ask the questions here.

Before I start configuring my first mail server, I would like to know if Linode allows me to use custom nameservers and set glue records? If yes, where and how to do that?

I guess the name server can be added by 'adding an NS record' in 'DNS Manager', but I am not sure what would be the subdomain.

For example, if I want to create a mail server with email accounts like, I think I should add an NS record with 'Name Server' to be, am I right? Then what would be the subdomain?

Also where is the glue record to be set?

Further more, I have several domain zones in Linode, running in the same Linode. I think I just need to install the mail server for one time, am I right? But then I have several domains (for example:,, and I would like email accounts like and How can I setup the Mail-in-a-Box?

Thank you for your help!
