WebMail Client Only System Requirements

Stewart -

I'm not sure what the system requirements for Atmail WebMail Client Only are.


  • Webmail Only Installations: Current Version

Atmail has not yet been installed.


The Atmail Application is provided in two modes, WebMail and Email Server + WebMail. With the WebMail Mode, you can use Atmail as an email client for your users. In the Email Server + WebMail you can provide email services from the Atmail application, and administer the system, including but not limited to modifying, deleting and creating Email Accounts.

  • You may use the WebMail mode to allow visitors to your Website to connect to their existing IMAP accounts.
  • You may use the Email Server and WebMail mode to create an Email Portal site where users can sign-up and create email accounts.

WebMail Client

As a WebMail Client, users can access Atmail via any browser or wireless device. Requests are handled by the Webserver (Apache) which runs the Atmail application.

User settings, Address Book, Scheduler tasks, profiles and account information are stored in a MySQL database. If using an IMAP account, all email messages will remain on the remote-mailserver.
