Since so many of us use Postfix I was wondering if we could solve the "Postfix needs userdb entry before delivery" problem by adding a method by which Postfix could lookup the mailbox in one of Cyrus' databases.
Originally I was thinking of pointing Postfix at mailboxes.db and adding a new DB class called "cyrus" to read from it, but I then wondered if the SASL database couldn't be used as well (since the mailbox names match the authorization names). Anybody have any thoughts, or done any Postfix hacking that could tell how easy or difficult this would be? The intent would be to give Postfix a native method for using one of Cyrus' databases as a "virtual" map. This would alleviate the requirement that adding users to Postfix is either pulling "double duty" by entering them twice, or turning off virtual user lookups entirely by using the "mydomains" entry. A third possibility would be to enhance somehow enhance Cyrus to pull it's User DB from LDAP (or some other DB Postfix already supports) and automatically create a user's mailbox they have been authorized and some "hasMailbox" flag has been set in the outside DB. Just an idea and some thoughts, anyone have any other feedback on this? -- Michael --
