An inefficient E-mail setup in a small office needs to be replaced with a better solution. I ask for your wise advice.
In a landscape architecture office, there are several Windows XP workstations for the architects to do their design work with. One of those workstations has a common E-mail client installed which works with one E-mail account provided by the ISP. It receives from it using POP3 and sends to it using SMTP, as commonly done.
Some incoming messages are "adressed" to the office and some are "addressed" to the various architects ( There is only one E-mail address). Thus anyone who wishes to read his incoming messages and send messages needs to physically go and use the workstation with the mail client. This, if you haven't guessed already, it somewhat uncomfortable for daily work in the office.
The requirements are that all messages, inbox and sent, would be available to access from all of the workstations and that it would be possible to send messages from all workstations, also. This is still using the single account provided by the ISP.
I would appreciate it if I was described of a setup that should answer these requirements effieciently, including the protocols and software involved. I am willing to learn whatever skills required for this.
Any suggestions and comments about anything, including the phrasing of this message, are welcome and your help will be accepted with gratitude.
