<p><P>PROBLEM TO BE SOLVED: To effectively utilize a mail server resource in an overall system to occurrence of a fault in a certain specific transmission destination mail server or path. <P>SOLUTION: This mail server system includes: a convergence control management part 120 for managing convergence control of an overall mail server system; a convergence statistical information collection part 119 for collecting convergence statistical information of each mail server 120; and a retry server 103 having a retransmission queue 117 having sufficient capacity for performing retry. When detecting a mail server causing a fault from the collected convergence statistical information, the convergence control management part 120 provides a direction of mail transmission restriction addressed to a faulty mail server to each mail server 102. The mail server 102 provided with the direction of the mail transmission restriction addressed to the faulty mail server transfers all the mails addressed thereto to the retry server 103, and transfers the received mails addressed to the faulty mail server to the retry server 103 until a restriction canceling direction is issued from the convergence control management part 120. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
