I'm currently looking for the correct parameter for Exchange Server 2019 to increase the timespan in which Exchange will accept a correct delivery of the complete mail.
We have a system (jBoss) which interacts with the Exchange by using James SMTP to communicate and accept mails via smtp. In my example I have sent a mail from the Exchange with 10 recipients in one mail. This mail then will be devided in 10 single mails (one each recipient). If one of these ten mails is not correctly processed within 10 minutes the whole mail will be sent again and again, which produces a loop effect in our system.
Is there a way to give my system more time to process by changing a parameter at Exchange which controls the time between sending a mail and the mail gets set into the retry queue?
Thanks!
I've tried changing the following parameters.
Exchange:
OutboundConnectionFailureRetryInterval to 20minutes
MessageRetryInterval to 30minutes
(this only minimizes the loop effect, not the 10 minutes in which the
mails have to be processed)
James SMTP:
ConnectionTimeout to 1800seconds (from 360)
