Abstract: PROBLEM TO BE SOLVED: To achieve stable service by avoiding congestion of a mail gateway and/or a mail system even when external conditions such as mail profiles and so on are changed, and to facilitate the estimation of the performance of the mail gateway.SOLUTION: A mail gateway monitors plural pieces of information in the internal processing of a program, and when the monitored information exceeds a threshold, the mail gateway determines the degree of influence on congestion for each mail received by the mail gateway, and preferentially regulates the processing of mails having a higher degree of the influence on the congestion. In addition, it visualizes the information on the internal processing of the program, which could not be conventionally monitored from the outside a server, and associates each processing to perform analysis and display.

Abstract: PROBLEM TO BE SOLVED: To solve the problem of an increase in storage capacity and network load of a mail server because of increasing mail traffic in mobile phone carriers.
SOLUTION: A relay device for relaying a mail transfer (SMTP communication) and a mail fetch (IMAP communication) is installed in a carrier facility network. The relay device compresses a mail including a header transferred from a mail transfer server, adds a new header to encapsulate the mail, and transmits the encapsulated mail to an IMAP server as a compressed mail. In response to a mail fetch request from a communication terminal, the relay device decapsulates and restores the compressed mail fetched from the IMAP server, and transmits the restored mail to the communication terminal. The relay device changes parameters, such as the mail size, to prevent inconsistency of IMAP commands from occurring in compressing/restoring the mail.
