To send or receive E-mail, a mail system environment must be
provided. Provide the mail system environment, including SMTP,
POP3, and DNS servers and so on, as required.
Notes on Security
E-mail uses the Internet, linking computers worldwide, as its
transmission path. Attention must be paid to security, in order to
avoid eavesdropping by third parties, or tampering as can in
general occur with electronic mail and other transmissions over
the Internet. Therefore, for important information, it is
recommended to employ other methods to guarantee security. In
addition, to avoid the receipt of unwanted E-mail, it is
recommended not to divulge the E-mail address to unrelated third
parties.
Preventing Receipt of Unwanted E-mail
The machine provides a feature to block malicious mail sent to a
user's address by an external third party of a known mail
address. This feature restricts the sender's address, by specifying
the domains from which mail may be received. For information
about restricting domains from which mail is received, refer to the
System Administration Guide, Chapter 9 (Domain Settings).
Notes on Receiving Mail
Depending on the data in a received E-mail, it is possible for there
to be insufficient memory, or for printing not to be possible. In this
case, either add more memory, or ask the sender to resend with a
lower resolution.
Notes on Mailbox
When total number of document pages stored in one mailbox
exceeds 15,000 pages, the following phenomena may occur.
Create a new mailbox to store documents. When the following
phenomena occur although the total document pages does not
exceed 15,000 pages, create a new mailbox to store documents.
• Document scanning speed decreases.
• Speeds to copy a document or move a document stored in
a mailbox decrease.
