Interface freezes for awhile when sending email notifications

Is anyone else experiencing delays when ServiceDesk triggers a notification event?  For example when a ticket is updated and a notification is sent to a user ServiceDesk will hang for 20-30 seconds.  This happens for all email notification events in ServiceDesk.

I am able to telnet from the SD+ server to port 25 on our email server (same subnet) with no delays.

Running SD+ version 9.0 Build 9039
