Postfix+Cyrus+Sasl Виртуальные ящики/домены как?

Я делал так - http://www.ugolnik.info/?p=340

Возможно это тебе поможет:

Here is an example of a virtual mailbox domain "example.com":

1 /etc/postfix/main.cf: 2 virtual_mailbox_domains = example.com ...more domains... 3 virtual_mailbox_base = /var/mail/vhosts 4 virtual_mailbox_maps = hash:/etc/postfix/vmailbox 5 virtual_minimum_uid = 100 6 virtual_uid_maps = static:5000 7 virtual_gid_maps = static:5000 8 virtual_alias_maps = hash:/etc/postfix/virtual 9 10 /etc/postfix/vmailbox: 11 info@example.com example.com/info 12 sales@example.com example.com/sales/ 13 # Comment out the entry below to implement a catch-all. 14 # @example.com example.com/catchall 15 ...virtual mailboxes for more domains... 16 17 /etc/postfix/virtual: 18 postmaster@example.com postmaster

Notes:

* Line 2: The virtual_mailbox_domains setting tells Postfix that example.com is a so-called virtual mailbox domain. If you omit this setting then Postfix will reject mail (relay access denied) or will not be able to deliver it (mail for example.com loops back to myself).

NEVER list a virtual MAILBOX domain name as a mydestination domain!

NEVER list a virtual MAILBOX domain name as a virtual ALIAS domain!

* Line 3: The virtual_mailbox_base parameter specifies a prefix for all virtual mailbox pathnames. This is a safety mechanism in case someone makes a mistake. It prevents mail from being delivered all over the file system.

* Lines 4, 10-15: The virtual_mailbox_maps parameter specifies the lookup table with mailbox (or maildir) pathnames, indexed by the virtual mail address. In this example, mail for info@example.com goes to the mailbox at /var/mail/vhosts/example.com/info while mail for sales@example.com goes to the maildir located at /var/mail/vhosts/example.com/sales/.

* Line 5: The virtual_minimum_uid specifies a lower bound on the mailbox or maildir owner's UID. This is a safety mechanism in case someone makes a mistake. It prevents mail from being written to sensitive files.

* Lines 6, 7: The virtual_uid_maps and virtual_gid_maps parameters specify that all the virtual mailboxes are owned by a fixed uid and gid 5000. If this is not what you want, specify lookup tables that are searched by the recipient's mail address.

* Line 14: The commented out entry (text after #) shows how one would implement a catch-all virtual mailbox address. Be prepared to receive a lot of spam, as well as bounced spam that was sent in the name of anything@example.com.

NEVER put a virtual MAILBOX wild-card in the virtual ALIAS file!!

* Lines 8, 17, 18: As you see, it is possible to mix virtual aliases with virtual mailboxes. We use this feature to redirect mail for example.com's postmaster address to the local postmaster. You can use the same mechanism to redirect an address to a remote address.

* Line 18: This example assumes that in main.cf, $myorigin is listed under the mydestination parameter setting. If that is not the case, specify an explicit domain name on the right-hand side of the virtual alias table entries or else mail will go to the wrong domain.
