piler/RELEASE_NOTES

1.4.5:
------

- Introduced 2 new variables in /etc/piler/piler.conf affecting piler-smtp

  ; max message size in bytes
  ; piler-smtp will reject any message that's bigger than this number
  max_message_size=50000000

  ; max memory in bytes piler-smtp uses for buffering messages
  ; when this limit is exceeded, no new emails will be accepted
  ; until the used memory for all in progress emails decreases
  ; below this level
  max_smtp_memory=500000000

  Be sure to adjust these values to your environment!

- Added read-only connection support for manticore
  If using sphinx, add the following to config-site.php:
  $config['SPHINX_HOSTNAME_READONLY'] = '127.0.0.1:9306';

- pilerimport supports Zimbra IMAP impersonation

  Generate the following base64 encoded string:
  (Be sure to use the actual usernames and password):

  pw="$( printf '%s\0%s\0%s' 'username' 'zimbra_admin_username' 'zimbra_admin_password' | base64 )"

  Then specify -u ZIMBRA -p "$pw" for pilerimport, eg.

  pilerimport -i imap.server -u ZIMBRA -p "$pw" ...

  Note that "ZIMBRA" is a special username, it indicates for pilerimport
  to actually use the imap impersonation for Zimbra.
