        Hello,
It looks like the "mail_always_cache_fields" and "mail_never_cache_fields" can be used to control dovecot's caching decisions. I cannot seem to find any documentation regarding how these fields should be used.
What are acceptable values for these fields? I am quite new to this so any help would be much appreciated.
Regards,
Siva
