Here is the situation: Imail 7.13, the server is set to gateway all mail to an external SMTP box. One list in particular is set to 50 recipients per message. Every time this list is sent it kills SMTP, meaning SMTP will not accept any more connections. Simply resetting the service fixes the problem. When digging through the logs I'm seeing the messages are being sent to the gateway server in groups of 5 rather than 50, which I think is strange. The only thing I haven't tested is to see the behavior of this list if the server is not set to use the gateway. I wanted to see if anyone here had any suggestions.
Here is a snippet of the log showing the list being sent. The list has 721 recipients and there are 143 batches of 5 messages being sent, as you see below. 12:05 10:08 SMTP-(00001520) Connect smtp2.crystaltech.com [216.119.106.211:25] (1) 12:05 10:08 SMTP-(00001520) 220 smtp2.crystaltech.com ESMTP 12:05 10:08 SMTP-(00001520) >EHLO axxxxxx.org 12:05 10:08 SMTP-(00001520) 250-smtp2.crystaltech.com 12:05 10:08 SMTP-(00001520) 250-PIPELINING 12:05 10:08 SMTP-(00001520) 250 8BITMIME 12:05 10:08 SMTP-(00001520) >MAIL FROM:<[EMAIL PROTECTED]> 12:05 10:08 SMTP-(00001520) 250 ok 12:05 10:08 SMTP-(00001520) >RCPT To:<[EMAIL PROTECTED]> 12:05 10:08 SMTP-(00001520) 250 ok 12:05 10:08 SMTP-(00001520) >RCPT To:<[EMAIL PROTECTED]> 12:05 10:08 SMTP-(00001520) 250 ok 12:05 10:08 SMTP-(00001520) >RCPT To:<[EMAIL PROTECTED]> 12:05 10:08 SMTP-(00001520) 250 ok 12:05 10:08 SMTP-(00001520) >RCPT To:<[EMAIL PROTECTED]> 12:05 10:08 SMTP-(00001520) 250 ok 12:05 10:08 SMTP-(00001520) >RCPT To:<[EMAIL PROTECTED]> 12:05 10:08 SMTP-(00001520) 250 ok 12:05 10:08 SMTP-(00001520) >DATA 12:05 10:08 SMTP-(00001520) 354 go ahead 12:05 10:08 SMTP-(00001520) >. 12:05 10:08 SMTP-(00001520) 250 ok 1039107961 qp 22755 12:05 10:08 SMTP-(00001520) gdeliver smtp2.crystaltech.com multiple (5) <[EMAIL PROTECTED]> 2997 Thanks, Dan Frazer To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
