Delayed e-mail

I have a domino agent that sent an e-mail blast on a certain days. The emails will be sent to another domino server (mail server), then it will go out to internet. I verified the e-mails went out on time from the original server, however, sometimes some e-mails got sent out later (could be 1 or 2 hours later) from the second domino server.

I track the message and can see in the second server, that the message arrival time is almost immediately after the first server sent the email. I believe this is indicated as "Message Arrival Time". However the e-mail does not get out quickly. The disposition time can be 1 or 2 hours later).

Is there any specific reason for this? Is it because the domino server (2nd server) is too busy delivering other email? Or is it because of the connection out to internet.? Two e-mail recipient from the same domain may receive the e-mail  on different time (1 or 2 hours apart).

Any help is appreciated.


Thanks in advance.

Concurrent transfer

If you're not seeing issues on the network or recipient systems then look at the notes.ini setting RouterAllowConcurrentXferToAll=1 this will increase the number of concurrent transfer threads out of the current NNN to the Internet.

Message Priority?

You don't note specific times, so this may be off-base - but Is it possible that the messages are marked 'low priority' and one of the mail servers are honoring the priority setting?

See Server Configuration doc -> Router/SMTP -> Advanced -> Controls -> Advanced Transfer Controls. Do the two server have the same 'Ignore message priority' setting? (If set to 'enabled' then this is not the issue)

The Server Configuration doc -> Router/SMTP -> Restrictions and Controls -> Transfer Controls tab contains the 'Low Priority mail routing time range' that is used when 'Ignore message priority' is set to 'disabled'.

Just a thought. This has caught me a couple times over the years....

It could be the receiving server that is overloaded
or might have a limit on number of emails it will accept from a single outside domain.

Delayed email

Thanks for all the responses. I think I may try to test RouterAllowConcurrentXFERToALL property in notes.ini and see the result.  I believe the messages are not set to low priority and the delivery time is not within the low priority mail delivery time range.


Kind Regards,

some more thoughts on data collection
Some good suggestions already.  Have you resolved the issue?

The delayed messages aren't being transferred for some reason.

"tell router show" will show the status of any transfer queues.   Could be some destinations in Retry because of a transfer failure.
   If in retry, check your Initial transfer retry interval on the Router/SMTP->Restrictions and Controls...->Transfer Controls tab of the configuration document.  Consider lowering this.  Default is 15 minutes.

"show tasks time" will show current transfers and how long they have been active.  Could be slow transfers to some destinations
