Goodday, We are running SMTP server on z/OS 1.9 on one of our LPARs. The emails from various LPARs are routed to this system via NJE. The emails are relayed to a MS-Exchange Server through this SMTP server.
We have been flooded by a process that needs to send out emails. We noticed that there is a +/- 15-20sec delay between each of the Delivery statements. The system is not CPU/ I/O constraint. Part of the SMTP log : EZA5476I 08/19/09 16:57:21 Delivered Note 00013657 to EZA5460I 08/19/09 16:57:24 BSMTP Helo Domain: XYZ4 EZA5474I 08/19/09 16:57:26 Received Note 00016015 via EZA5460I 08/19/09 16:57:31 BSMTP Helo Domain: XYZ4 EZA5474I 08/19/09 16:57:32 Received Note 00016016 via EZA5476I 08/19/09 16:57:36 Delivered Note 00013658 to EZA5460I 08/19/09 16:57:39 BSMTP Helo Domain: XYZ4 EZA5474I 08/19/09 16:57:40 Received Note 00016017 via EZA5460I 08/19/09 16:57:46 BSMTP Helo Domain: XYZ4 EZA5474I 08/19/09 16:57:47 Received Note 00016018 via EZA5476I 08/19/09 16:57:50 Delivered Note 00013659 to EZA5460I 08/19/09 16:57:54 BSMTP Helo Domain: XYZ4 EZA5474I 08/19/09 16:57:55 Received Note 00016019 via EZA5476I 08/19/09 16:57:59 Delivered Note 00013660 to EZA5460I 08/19/09 16:58:02 BSMTP Helo Domain: XYZ4 EZA5474I 08/19/09 16:58:04 Received Note 00016020 via EZA5460I 08/19/09 16:58:09 BSMTP Helo Domain: XYZ4 EZA5474I 08/19/09 16:58:10 Received Note 00016021 via EZA5476I 08/19/09 16:58:14 Delivered Note 00013661 to Is there any parameter that we perhaps have not set correctly to ensure the notes get delivered sooner ?
