I'm attempting to upgrade my Dovecot installation to 2.3.2.1. My SSL
certificate authority provides a bundle containing their CA, plus
intermediate CAs, which I configure using the 'ssl_ca' option. The
comments in the configuration file say to only set this when you're
requiring client certificates, which I'm not, but fetchmail complains
with a "Server certificate verification error, Broken certificate chain"
error if that setting is not set. This works fine with Dovecot 2.2.34.
Try creating your certificate by appending all your server and
intermediate certs in this order into one file
server certificate
intermediate certificate 1
intermediate certificate 2
...
where the chain works toward the root CA. You don't need the root CA as
your client ought to anchor the chain with its own CA store. Then set
the value of ssl_cert to this file.
