I upgraded to Build 7692 last week.  We had no problems before we were instructed to upgrade from Build 7242 except for one IMAP user who had issues with viewing his email on his iPhone.  

Since the upgrade, I have noticed that the amount of time that it takes for emails to be sent out or delivered is much longer (sometimes 3+ minutes).  They are either sitting in the SPOOL with a SPAM CHECK being performed or the email sits in the OUTBOX on their computer.   I have sped up the time a little by disabling SPAM CHECK on OUTGOING emails.    Nothing has changed (equipment & settings) from before the upgrade to afterwards.  

Is anyone else experiencing the same issue?   

Thanks,
