Thanks Aki,
Just a followup regarding this. I set "mail_always_cache_fields" to the following in dovecot configuration file:
mail_cache_fields = flags,imap.body,imap.bodystructure mail_always_cache_fields = imap.body,imap.bodystructure
I run the following command to ensure that these configurations have an effect on the caching behavior:
doveadm index -u bob INBOX
I notice that "data->wanted_fields" in index-mail.c is as follows:
(MAIL_FETCH_STREAM_HEADER | MAIL_FETCH_STREAM_BODY | MAIL_FETCH_RECEIVED_DATE | MAIL_FETCH_SAVE_DATE | MAIL_FETCH_PHYSICAL_SIZE | MAIL_FETCH_VIRTUAL_SIZE | MAIL_FETCH_UIDL_BACKEND | MAIL_FETCH_GUID | MAIL_FETCH_POP3_ORDER)
Since I made the changes above I except data->wanted_fields to contain MAIL_FETCH_IMAP_BODY and MAIL_FETCH_IMAP_BODYSTRUCTURE. This tells me that these fields are not being cached?
Am I doing something wrong here?

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.

Siva
Hi!
You can use the same field names as for 'doveadm fetch'. Please note though that you need to rm dovecot.index.cache file after changes, this has only been fixed in 2.2.34 dovecot release.
