How to Install SquirrelMail on CentOS 7

We’ll show you How to Install SquirrelMail on CentOS 7. SquirrelMail is one of the most popular Web-based email clients written in PHP. It has built-in pure PHP support for IMAP and SMTP, and it is designed to render all pages in pure HTML 4.0 with no JavaScript required, for maximum compatibility across browsers. Its installation and configuration is pretty simple. Note that if you have a VPS with WHM/cPanel or DirectAdmin, SquirrelMail comes preinstalled and ready to use with these control panels. Installing  SquirrelMail on CentOS 7, its not complex task, follow our guide below and you should have it installed in few minutes.

  1. hi rose

    I’ve setup my server exactly like you wrote in this post and i got no error messages or warning messages …but if i access the web interface i got 404 error? and if i check my HTML folder there isn’t any “webmail” folder

    Do i need to create this folder manualy ? also during the config setup on Server setting

    what is the correct input if we used subdomain on the server ..let say my domain is mail.rosehosting.com

    is it mail.rosehosting.com or just rosehosting.com

    Thanks

    • According to the tutorial, SquirrelMail is installed in the /var/www/html/squirrelmail directory (not “webmail”) and your SquirrelMail should be accessible at http://yourIPaddress/squirrelmail.

      Also, under the Server settings, in your example, you should use rosehosting.com as a domain name instead of mail.rosehosting.com.
