What is a valid place for my own environment variables for
submit program? I have found very nice patch in the list archive
and used it, but the variables placed in courierd or esmtpd config
files are not a *permanent* readable. When I send a message via
telnet, then submit program is invoked 2 times, but it can read
my variable only at the beginning. When I send a message via
SqWebmail, then submit can't see my variables at all.
