Hello.
Adding further information that might be relevant to spot the problem.
(1)
I'm not using the certificate provided in the installation, but created
one using my own CA.
The output from openssl would be 2 files ("cert" and "key") while courier
uses only one, so I combined the two into a single "imapd.pem" file, and
also added a third part (about DH parameters).
[Is this the correct procedure (and why is it different from, say,
"postfix" which uses the two files approach)?]
(2)
Attached, you'll find the "printenv" output from my configuration.
Does this contain some information (such as contradictory or missing
settings) which could explain the problem?
(3)
I'm not using "couriertcpd" but "tcpsvd" as a tcp server; and the application
is started with the following command:
/usr/bin/tcpsvd -c 20 -C 5 192.168.20.11 993 \
/usr/bin/couriertls \
/usr/lib/courier/courier/imaplogin \
/usr/lib/courier/authlib/authdaemond.ldap \
/usr/sbin/imapd
Thanks and best regards,
Gilles
