Hi,
To force all people sending mail through my exim smtp server to use TLS, I
added the line
hosts_require_tls = *
to my exim.conf.
But when starting exim, I get
<<Exim version 4.20 uid=0 gid=0 pid=11837 D=fbb95cfd

Exim configuration error in line 32:

Any idea what I am doing wrong?
Many thanks for any hints in advance!

P.S.: I didn't see a hint how to avoid this in
http://www.exim.org/exim-html-4.10/doc/html/spec_29.html#IX1568 and
