Hello Noel,

When I run "export" on the shell, I can see that both USER and LOGNAME are 
defined. But I think this information isn't very helpfull, since many people 
(so am I -> JAMES-662) call the sendmail-wrapper from PHP (or any other 
CGI-script) within the webserver. The enviroment here may be completely 
different (in my case (and maybe in many others) USER and LOGNAME are _not_ set 
in the webserver-enviroment).

IMHO your script a least should make arrangements for the case that USER isn't 
set (don't know if Python has an exception-handling - I'm no Python-programmer) 
and set a default-value instead in case of emergency ;-)

Debian 3.0 (a.k.a woody)

Let me guess: On the shell?
