In Zeta there are included two MUAs (Mail User Agents), BeMail
and Beam. These two applications are used to read and write e-mail
messages.
To be able to send e-mails to various MUAs on differents platforms,
there has been made a standard e-mail format, RFC 2822. The e-mail's
letterhead contains several fields: From:, To:, Cc:, Message-ID:,
Date:, Received:, etc. The information is used by the MTAs (Mail
Transfer Agent) to transfer your mail to the receivers. MTAs will
add information about it self in the received field, as the mail
passes it. You can than see how many MTAs the e-mail had to pass
before reaching you.
E-mails are sent and received over IP/TCP with the use of the following
protocols SMTP, POP and IMAP. BeMail supports both POP and IMAP,
Beam only POP, but both uses SMTP for sending e-mails.
To be able to send and receive e-mails you first of all need to
have an e-mail account. This account's configurations should be
added to the MUA you choose to use:


Both MTAs support multiple e-mail accounts.
