These are general instructions; instructions for specific mail clients will be included in separate FAQs.
For the sake of examples, we will use the domain "yourdomain.com". Any instance of "yourdomain.com" should be replaced by your actual domain name.
Your users may access their mail via POP or IMAP by entering "mail.yourdomain.com" as their incoming mail server, and "username@yourdomain.com" as their POP or IMAP username. (Note: certain older mail programs may require that they use "username%yourdomain.com" instead. As far as the CommuniGate server is concerned, either is valid.) They may also access their mail via the web by pointing their web browsers at:
http://mail.yourdomain.com/
They may also send mail through the CommuniGate server by entering mail.yourdomain.com as their outgoing, or SMTP, server. There are, however, two requirements they will have to meet to do so. First, they must be using an email client that supports SMTP authentication. Second, they must not be using an ISP that blocks them from using external SMTP servers (Earthlink, for example, will not permit their users access to SMTP servers outside their network). If the user does not meet either of these requirements, it should be possible to send through the ISP's mail server.
