Python thread problem

[Ravi]

Hi all,
         I am running a python cgi which inturn calls a python thread.
This python thread executes some commands and sends an email to the
admin.
         I am facing a strange problem, in the cgi script when I set
the python
thread to run as Daemon, then it does not send the email, but when I
donot set the thread as daemon, it does send the email.
        Can somebody help me as to this behaviour ? 

I am running the cgi and python scripts on linux. The only problem I
can see is that the email module is present in python2.3 and I have
python 2.3 installed at /usr/local/lib/python2.3 and also have
python1.5 installed at /usr/lib/python1.5.

Is this the problem for such behaviour? Is there a way to fix ? Could
somebody help me out please?

Thank you in advance.

Ravi.
