Postfix Mysql maps
Is it possible to use the Mysql maps in Zimbra's postfix for example to define the restrictions like "check_sender_access" ?
Example of postfix_recipient_restrictions.cf
Thanks in advance for the help!
Edit: I want add a thing: I don't want to use the embedded mysql of zimbra, but another istance. On Ubuntu system, I know the postfix-mysql package, but I don't know if it is possible to use with zimbra.
