When an Exchange 2013 Server is upgraded to SP1, mailflow will stop / MailEssentials can't be installed on Exchange 2013 SP1TT / JIRAID
1653How to Identify
After the installation of Exchange 2013 SP1 the mailflow will stop - removing MailEssentials will establish mailflow again.
Trying to install MailEssentials again (or on a fresh Exchange 2013 SP1 server) will fail as the Agents can't be installed. The ek27wiz.log doesn't show any errors.
But when manually trying to install one of the agents you get an error:

The TransportAgentFactory type "ContentSecurity.ExchangeAgents.GfiAsSmtpAgentFactory" doesn't exist. The
TransportAgentFactory type must be the Microsoft .NET class type of the transport agent factory.
