Need Email Server Solution for MyCompany.com using a Dynamic IP Address
MyCompany.com is small 5-person company experiencing a moderate growth rate. We expect to add 5 more employees in the coming months. The requirements are:
• The ability for each employee to access their own email from their desktops.
• The ability to add new users quickly and inexpensively.
• Virus protection for all users.
• Reduce Spam to employees.
• Access company email via a Web browser from anywhere on the Internet.
At the time of initial installation, Mycompany.com has 5 employees:
1. Chris: Admin
2. Jennifer, Jakub, Christina and Philip.
Each employee has a computer that is connected to a small local network (LAN). Only a single computer in the office has access to the Internet via a single ADSL connection to the local Internet Service Provider. In addition, all email accounts, as well as the web site for “mycompany.com“ are being hosted by our local Internet Service Provider.
In the near future, mycompany.com is planning to add 5 new employees with plans to add several more users in the future. It has become apparent to everyone that each user needs immediate access to his/her email account, as well as browsing access to the World Wide Web.
Mycompany.com currently has 8 virtual email addresses and 7 POP accounts as follows:
• firstname.lastname@example.org (forwards to email@example.com)
• firstname.lastname@example.org, and;
The schematic diagram of our system is in the picture attached.
We need a Linux Mail Server solution for mycompany.com that run on Fedora 6 or any other distro like OpenSuse, Ubuntu, etc.
We need “Remote Account” feature for mycompany.com that allow our email server to remotely connect to our only one POP account located in the ISP server and pull all incoming emails into the appropriate user's local mailbox. The employees at mycompany.com can also send email directly through our Mail Server or using our ISP by SMTP relay.
Reason to have only one POP Mail Account:
Currently, our ISP charges them $30 USD per POP account per year, thus their 7 POP boxes currently cost mycompany.com $210 dollars annually.
Instead of setting up our Mail Server to pull emails from the 7 separate POP accounts costing mycompany.com $210 per year, we set up a single POP account for mycompany.com at our ISP seerver, create a “wildcard” alias for it that will result in email@example.com being forwarded to the single POP account, and close all of the other POP accounts. Now that “firstname.lastname@example.org” is being sent to a single POP account, Chris can now use our mail server to connect to the ISP POP account, download all of the messages, and forward them to the appropriate users.
Several weeks later, Chris determines that the email address “email@example.com” needs to be added for accounting purposes. Chris adds the account to our mail server, and “firstname.lastname@example.org” is live and working immediately without the need to contact our ISP or pay an additional $30 per year.
Please give us advice and detailed instructions with Linux Code or better the configuration files to do this job. Thank you.
