5. Setting up an Data Tank Gateway Mail Server
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 Data Tank Gateway
The Data Tank Gateway mail server supports POP (Post Office Protocol Version 3) and
IMAP (Internet Message Access Protocol) for retrieving and SMTP (Simple Mail Transfer
Protocol) for sending e-mails.
Options
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 Data Tank Gateway; yourhost.
no-ip is the hostname that you selected at the Dynamic DNS provider).
Data Tank Gateway in everyday use
Explanation
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. Unlike
the POP3 protocol, the e-mails generally remain on the
server and are only transferred to the client as required.
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 POP!
The SMTP protocol is used to exchange e-mails within
computer networks. SMTP is mostly used to send and
forward e-mails.
