Turns out this was an openldap config issue .. connecting to ldap via self signed cert and had
/etc/openldap/ldap.conf as
TLS_CACERT /etc/dovecot/ldap_ca TLS_REQCERT allow TLS_CACERTDIR /etc/openldap/certs
SASL_NOCANON on
Seems what ever gets generated in TLS_CACERTDIR is problem .. commentng that out seems to have resolved issue ..
Matt Bryant mailto:matt@the-bryants.net 13 September 2018 at 12:52 pm Not sure if this is dovecot or not but can find very little ie no info around on this ... and added the pem file into /etc/pki/ca-trust/source/anchors and run udpate-ca-trust .. all works ok .. (this is on centos 7 btw)
So wanted to change the hostname away from ip-x-x-x-x to something a little bit more descriptive .. but then kaboom .. doesnt work any more and the following errors are seen.

why would a hostname change make any difference here .. the certs specified in dovecot config are all complete in their chain so not sure what its trying to do ... set hostname back to original works find .. so something is obviously tied or keyed to hostname though cant find anything specific
anyone seen anything like this at all ??
