The followings is the imap and cache related entries.  Does the
imap_idle or imap_keepalive need to set explicitly in current HEAD
version of mutt?

# refresh imap inbox
# set imap_keepalive=300

set imap_list_subscribed="yes"

# Don't wait to enter mailbox manually
#unset imap_passive

# Automatically poll subscribed mailboxes for new mail (new in 1.5.11)
set imap_check_subscribed=yes

# Reduce polling frequency to a sane level
set mail_check=300

# And poll the current mailbox more often (not needed with IDLE in post 1.5.11)
set timeout=300

# keep a cache of headers for faster loading (2.5.9+?)
set header_cache=~/.mutt/cache/headers
set message_cachedir=~/.mutt/cache/bodies

set message_cache_clean=yes
