The "tls-support" option cannot be used because a required compile-time option was not set.

[Bernd Prager]

Hi everybody,

I would appreciate some help in setting up qpopperin using SSL.
I'm using RedHat7.0 kernel 2.4.7-10, qpopper4.0.3, cyrus-sasl-1.5.27
and openssl-0.9.6b-8. I configured qpopper with
./configure --with-openssl --enable-specialauth --enable-timing
and it compiled without warning or errors.
I genererated the /etc/mail/certs/cert.pem file and changed popper.config to
set tls-support = stls
set tls-server-cert-file = /etc/mail/certs/cert.pem

and edit the /etc/xinet.d/pop3s file to
service pop3s
{
  socket_type   = stream
  wait          = no
  user          = root
  server        = /usr/sbin/stunnel
  server_args   = pop3s -l /usr/sbin/popper -- -R -s -t /var/log/pop3s -f
/etc/popper.config
  log_on_success += USERID
  log_on_failure += USERID
  nice
}

When I try to access it I get the error message:
Mar 19 01:04:19 myhost popper[18561]: The "tls-support" option cannot be
used because a required compile-time option was not set.  See the
Administrator's Guide for more information (line 79 of config file
/etc/popper.config) [pop_config.c:1408]

I doesn't even write the logfile and doesn't give me further error messages
either.

Can anybody give me a hint what I'm doing wrong or what I have to do to nail
the problem down?

Thanks,
