SUMMARY

Under certain conditions you may need to increase the amount of email that can be delivered concurrently into users mailboxes. The postoffice connector service is responsible for the delivery of email from the SF Outgoing queue to the mailbox. This change is done through a change in the Windows registry.

DETAIL

To change the number of threads allocated to the postoffice connector you need to change the following value. The service does not need to be restarted. By default the value is set to 10. If you are increasing this value, try setting to 32 or 64 at most.:

For 64bit Windows:

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Mail Enable\Mail Enable\Connectors\SF]
"Maximum Pickup Threads"=dword:0000000a

For 32bit Windows:

[HKEY_LOCAL_MACHINE\SOFTWARE\Mail Enable\Mail Enable\Connectors\SF]
"Maximum Pickup Threads"=dword:0000000a
