[Discuss] Postfix ailiaes question

[kentborg at borg.org (Kent Borg)]

How do I get postfix to append some mail to a file? In the past I have 
put in /etc/aliases something like:

 ?? some-string: /path/to/file

And when I sent an e-mail to "some-string at borg.org" the mail would get 
appended to that file. But in my current server when I try to do I see 
in /var/log/mail.log I get a warning that it can't create 
/path/to/file/some-string.lock and the error that it can't open the file 
/path/to/file/some-string, permission denied in both cases.

I have tried chowning the file some-string to postfix:postfix, to 
root:root,? to mail:mail, to kentborg:kentborg (the parent directory, 
too), but haven't found a working setup

To save to a file what ownership and permissions does postfix need?


Thanks,
