AHA! That's it. I am indeed using LDAP for authentication via /usr/
lib/postfix/dict_ldap.so

I temporarily disabled ldap and relayed a message, and no errors.

Sorry to have occupied so much of your time, but perhaps this will
help someone else avoid a similar investigation. What was really
confusing is that these errors were not reported with postfix 2.3.3,
despite an identical configuration.

So, just to finish this, is it correct that, assuming I want/need to
use postfix 2.3.8 with dict_ldap.so, I can only avoid these errors by
disabling chroot or building proper usr/lib/sasl2 directory within /
var/spool/postfix? Are those my only two options?

Thanks so much.
