Thanks tom!
that seemed to work.
i have another question, regarding jail and sendmail.
my server hostname is requiem.digi-data.com.
i have jailed my sendmail.
here it comes... should i use the same hostname as my real OS
requiem.digi-data.com, for the jail hostname- requiem.digi-data.com ?
would that be wise?
Thanks
