Zarafa 7.1 vs 7.0Steve Hardy

• zarafa-search (TIPKAZI)• zarafa-spooler / zarafa-dagent python plugins• ldap_uri• zarafa-stats –session / --users / --servers / --company / --system• Offline database change• Multithreaded zarafa-backup• Dagent: support for rfc1891 delivery reports• Dagent: filtering of duplicate recipients• No major DB changes• Multiserver reverse proxy

New in 7.1

• Used to be zarafa-indexer, but so different that we renamed it• Major differences:

– No more support for one-to-N in cluster. So you must run one zarafa-search per cluster node. We could add this again in the future if you really need it

– No more ‘scanning’ of all stores every 5 minutes. Mode of operation is:• First, scan all stores• Enter ‘incremental mode’• Only index changes (every 5 seconds)

– More powerful, compressed indexes in /var/lib/zarafa/index

– You must connect from zarafa-server to /var/run/zarafa-search instead of /var/run/zarafa-indexer (this is default now in 7.1 RC1)

– Streaming of data from archive servers

Zarafa-search

• Allows zarafa-dagent and zarafa-spooler to do certain things by adding python plugins

• No restart required when adding plugins• Plugins currently available:

– Spooler: add disclaimer to all outgoing emails

– Dagent: convert incoming image attachments to JPG

• Other things that are possible (examples!!!):– Add rules that are forced for all users

– Drop or forward messages for some reason

– Do OCR on incoming images and file them in the appropriate folder

• Will publish developer manual later• Will probably mainly be used by us

Python plugins

• Simple option that has been asked a lot: allows multple LDAP servers to be specified

• Uses libldap logic to connect (first try the first one, then the next)• Create possibilities for really bad things to happen:

– First LDAP Server is OK

– First LDAP server fails

– Zarafa-server connects to second LDAP server

– Oops, this ldap server is empty

– All stores are deleted

ldap_uri

• Better output now from zarafa-stats in table form

Zarafa-stats

• After upgrade, will upgrade engine from MySQL 4.1 to MySQL 5.5• Procedure the same as in Zarafa 7

– Upgrade starts in background

– Connects online while background upgrade is in progress

– Should take less time than the Zarafa 7.0 upgrade

Offline database change

• Backups STORES in parallel• So, backing up one store cannot be done multithreaded• Should be useful up to N threads if you have N physical (non-

mirrored) discs

Multithreaded zarafa-backup

• Filter duplicate recipients– Eg sending group to ‘great guys’ and ‘super smart people’ only delivers

ONE email to steve instead of two

• Support rfc1891 delivery reports– So that means that we report OK delivery to postfix, and postfix relays

that back to the sender

– Quite unreliable since all intermediate SMTP servers must support rfc1891

Dagent

• Priority queue– Use file:///var/run/zarafa-prio but only if you understand what you’re

doing

• LDAP paging support

• Post-MSR offline resync– Offline sync code detects MSR of store and resyncs with new server

• MR autoresponder– Responds to emails received in inbox. Default operation mode for OL2010

• Auto-create archive store via LDAP– Instead of creating archive store seperately
