Note that Python has a limit for nesting functions:

>>> depth = 0
>>> def callself():
...     global depth
...     depth += 1
...     callself()
...
>>> try:
...     callself()
... except RuntimeError, e:
...     print "depth", depth
...     print e
...
depth 999
maximum recursion depth exceeded

>>> 999/365.25
2.7351129363449691

This means that your app will probably crash in less than three years.
Would that be a problem on W2K ?

If so, a loop could go much longer:

while True:
    ipconfig_email()

Seriously, you should reconsider the OS features.
