Mails slow to transfer, long delays noted

Problem

The customer reported that mails to one particular Domain were taking a long time to transfer, in one case an 8 hour delay was noted.

Symptom

Slow Mail transfer


Cause

Multiple concurrent threads not set on this connection

Diagnosing the problem

Reviewing the console logs with the following parameters

DebugRouter=3
Log_mailrouting=40
We could see the following:

"Router: Transfer queue to server <server name> is already pending (1 active, 0 ready)"

So at least 1 mail was pending but there were no indications as to why.

Resolving the problem

Enable Notes.ini parameter:

RouterAllowConcurrentXferToAll=1

On the connecting server, restart the router.

Mails then begin to transfer much quicker

Title: Enabling concurrent transfer threads and the notes.ini parameter RouterAllowConcurrentXferToAll

By enabling RouterAllowConcurrentXferToAll, multiple concurrent threads will also be used for Domino servers transferring NRPC mail over a Connection document, for example when transferring to another Notes domain. Connection documents are assumed to be a slow connection and will not utilise the concurrent threads without this notes.ini parameter set.
