How can I run both Cyrus and Zarafa on a single server?

To run both Zarafa and Cyrus on a single machine, please follow these steps:

• To use Postfix with multiple transport providers you need to use a transport table. Add the following line to the Postfix master.cf file:
  

  zarafa  unix   -      n       n       -       -      
  pipe user=vmail argv=/usr/bin/zarafa-dagent ${user} 

• Comment the mailbox_command and mailbox_transport in the Postfix main.cf. Add the following line to the Postfix main.cf:
  

  transport_maps = hash:/etc/postfix/transport 

• In the file /etc/postfix/transport you can add email addresses with the corresponding transport provider. For example:
  

  m.oostergo@zarafa.com   zarafa 
  j.lewis@zarafa.com      cyrus 

• After you have made changes to the transport table you need to run the command "postmap /etc/postfix/transport" to create the hash file.
   

Now all mail for m.oostergo@zarafa.com is delivered to Zarafa and the email for j.lewis@zarafa.com is delivered to Cyrus.
