Freecom Storage Gateway (FSG)
5.8 Setting up an FSG Mail Server
GB
An e-mail server, or simply mail server, handles e-mails. It is responsible for receiving,
sending, saving or forwarding e-mails.

Note: In the name of spam protection, some freemail providers refuse to
accept e-mails received from dynamic DNS hostnames. Please keep this in
mind when sending e-mails!
Configuring the FSG
The FSG mail server supports POP3 (Post Office Protocol Version 3) and IMAP (Internet
Message Access Protocol) for retrieving and SMTP (Simple Mail Transfer Protocol) for
sending e-mails.
POP3
IMAP
SMTP
Set up a Dynamic client under Services -> Dynamic DNS if you have not already done so.
Your e-mail address corresponds to the hostname that you set earlier, e.g.,
xxx@yourhost.no-ip.org (xxx is a user that you previously added on the FSG; yourhost.no-
ip is the hostname that you selected at the Dynamic DNS provider).

Communications protocol for retrieving e-mails using an
e-mail client. POP3 allows the user to retrieve and delete
e-mails on the server. A permanent connection to the
POP3 mail server is not required. The fetched e-mails are
stored locally and available offline.
The IMAP protocol allows the user to access and manage
e-mails directly on the server using an e-mail client. Un-
like the POP3 protocol, the e-mails generally remain on
the server and are only transferred to the client as re-
quired. In other words, you need an Internet connection
to read the e-mails. IMAP provides detailed access control
to mailboxes as POP3.
Note: Many freemail providers only support POP3!
The SMTP protocol is used to exchange e-mails within
computer networks. SMTP is mostly used to send and
forward e-mails.
