Server + WebMail System Requirements

Stewart -

PROBLEM
I'm not sure what the system requirements for Atmail Server + WebMail are.

ENVIRONMENT

  • On-Premise Server + WebMail Installations: Current Version

CAUSE
Atmail has not yet been installed.

RESOLUTION

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 + WebMail mode to create an Email Portal site where users can sign-up and create email accounts.

Email Server

You can use Atmail to setup a complete Email Server for your company. Users can access accounts created in Atmail with external clients (Outlook, Eudora, etc.), or using the WebMail interface of Atmail. The Administrator can maintain user accounts and system settings via the WebAdmin interface.

In Server Mode, Atmail functions as a complete Email system. Users can optionally sign-up online and have full access to their email account via both the WebMail interface and using desktop POP3/IMAP clients. Using the WebAdmin interface, Atmail can be configured to run as a complete mail-server system for an ISP, company or as an office mail-server. The software can optionally be setup as a Hotmail style service with a open signup page, to offer WebMail services online.

User settings, Address Book, Scheduler tasks, profiles and user authentication information are stored in a MySQL database. Messages received by Atmail are stored on the local filesystem in Maildir format. POP3, IMAP, and WebMail retrieve the messages from the Maildir database.

Hardware Requirements

Note that specified HDD space is EXCLUDING space allocated to users for mailbox and storage.
Eg. 40GB for installation and logs, plus (1000 users x 1GB storage) = 1040GB minimum.


Recommended: Dual Core Processor 8GB RAM 100GB HDD
