When the user upgrades from firmware versions below R77.20.81 (inclusive) to R77.20.85-87 (990173043 inclusive), the service timeouts change incorrectly for the service IMAPS.  

**For 1500 appliances:**   
When the user upgrades from firmware versions below R80.20.01 (inclusive) to R80.20.05, the service timeouts change incorrectly for the services IMAPS and POP3S.
