Restriction of Sending and Receiving Emails

Restriction Condition from Outside of SFC Networks

Restriction of Sending Emails

  • The maximum file size for sending an email is just 200MB.
  • To prevent spam, the SFC mail server cannot be used as a send mail server from outside of SFC without the authentication.
    • If there is no problem with the CNS login name and IMAP/SMTP-AUTH Password authentication on sending emails, users can send emails. Please refer each example of setting mails.
    • Many ISPs restrict sending emails on the 25 port used for SMTP. IMAP4 users and POP3 users should select "Submission Port" or "SMTP over SSL".
