TLS exim4 timeout

Hi,

I was just setting up exim4 with TLS following and cross-correlating a
number of online tutorials and the exim documentation. I was using
swaks to test the setup up and get this:

psyc@delphi:/dev$ swaks -a -tls -q AUTH -s localhost -au psyc
Password: **********
=== Trying localhost:25...
=== Connected to localhost.
<- 220 delphi ESMTP Exim 4.60 Fri, 18 Aug 2006 15:21:56 -0400
-> EHLO delphi
<- 250-delphi Hello localhost [127.0.0.1]
<- 250-SIZE 52428800
<- 250-PIPELINING
<- 250-STARTTLS
<- 250 HELP
-> STARTTLS
<** Timeout (30 secs) waiting for server response
-> QUIT
<** Timeout (30 secs) waiting for server response
=== Connection closed by foreign host.

I've read elsewhere that this can be due to entropy issues (creating
random seeds for gnutls) however I've found nothing to lead me to how
to fix it, increase entropy, or to verify if that is in fact the
problem.

Any help is much appreciated.

Thanks,
John
