Hello, I have been running for a long time a service that uses
IdTCPServer and IdSMTP.

IdTCPServer receives strings, that are passed to the main thread with a
IdNotify, and saved to files.

The main thread process the strings in files at intervals, send
confirmations using a IdTCPClient and if detect an error, send an
email, from the main thread.

I have updated to latest version of Indy four months ago, and again
last week to see if a prolem is solved, but no lucky.

My problem is that the service, that has been running fine for years,
freeze sending an email.

I save the status text of the smtp server in a file, and I observe that
allways the freeze happens after the connection to the stmp server is
established:

03/09/2015 08:48:21.528    SMTP -> Connected.  ===> Freeze

My question is if there is some change in Indy that can affect This
components and produce this behaviour?
