Q: Postfix sacl_check

I am testing mail service on a Lion Server, and am currently seeing several entries related to sacl_check in mail.log.

 

More specifically, if I send a message to an external email address (ie:  "foo@me.com"), I see the following entries:

 

Aug  5 12:23:26 testserver postfix/smtpd[56752]: sacl_check: mbr_user_name_to_uuid(foo) failed: No such file or directory

Aug  5 12:23:26 testserver postfix/smtpd[56752]: sacl_check: mbr_user_name_to_uuid(@me.com) failed: No such file or directory

Aug  5 12:23:26 testserver postfix/smtpd[56752]: sacl_check: mbr_user_name_to_uuid(foo) failed: No such file or directory

 

Aug  5 12:23:26 testserver postfix/cleanup[56756]: sacl_check: mbr_user_name_to_uuid(foo) failed: No such file or directory

Aug  5 12:23:26 testserver postfix/cleanup[56756]: sacl_check: mbr_user_name_to_uuid(@me.com) failed: No such file or directory

 

Aug  5 12:23:27 testserver postfix/cleanup[56756]: sacl_check: mbr_user_name_to_uuid(foo) failed: No such file or directory

Aug  5 12:23:27 testserver postfix/cleanup[56756]: sacl_check: mbr_user_name_to_uuid(@me.com.com) failed: No such file or directory

 

The messages are being delivered successfully, but I don't understand these sacl_check messages from smptd and cleanup. I've not seen them in versions of OS X server prior to Lion.

 

Can anyone help?

    Just disable/comment out:

     

    #virtual_alias_maps = $virtual_maps hash:/Library/Server/Mail/Config/postfix/virtual_users

    #virtual_alias_domains = $virtual_alias_maps

     

    It should fix this problem

    Hi All

     

     

    The sacl_check: mbr_user_name logs are occuring due to the fact that you send mail

    to an alias of the original username.

     

    Lets say you have an account "John@xxxx.com " and John wants to send mail to the outside world without showing his actual username (which obviously is John) but with an alias Info@xxxx.com .

     

    When sending mail to John@xxxx.com no sacl_check error is logged because the actual username is existing on the server side (uuid).

     

    When the receiver replies to Info, the system must lookup the parent of the alias. (info is not an actual username, so with no uuid) then the sacl_check will generate an error log.

     

    The mail will be transferred anyway so there is no problem, i think its just a warning.

     

     

    Kind Regards

    We have also this problem, but it only accures when sending to a @hotmail.com adres.

    I don't think your solutions have anything to do with this. Any idea where to look then ?

     

    And we are using a account that is not using a alias.

     

    The user is not using an alias, but the acocuntname as it mailadres, it sent to a hotmail account.

    And how can this mail server see it is a alias on a other domein / mailserver ?
