I want to trap known spam messages addressed to "info@mydomain" and "spam@mydomain". I created two maildirs for those addresses, then I set up dot-courier(5) files like this:

$ cat /etc/courier/aliasdir/.courier-info /var/lib/courier/maildirs/.info

I want to be able to look into those folders from my normal account, so I tried to set them up as shared maildirs: I followed the instructions in maildirmake(1), then I changed the permissions to user "flavio" and group "daemon" to allow Courier to write to them. Here it is:

$ ls -lA /var/lib/courier/maildirs/ total 20 drwx------ 2 daemon daemon 4096 2005-06-19 11:18 cur drwxrwx--- 5 flavio daemon 4096 2005-06-19 11:18 .info drwx------ 2 daemon daemon 4096 2005-06-19 11:18 new drwxrwx--- 5 flavio daemon 4096 2005-06-19 11:18 .spam drwx------ 2 daemon daemon 4096 2005-06-19 11:18 tmp

$ ls -lA /var/lib/courier/maildirs/.info/ total 12 drwxrwx--- 2 flavio daemon 4096 2005-06-24 11:05 cur -rw-rw---- 1 flavio daemon 0 2005-06-19 11:18 maildirfolder drwxrwx--- 2 flavio daemon 4096 2005-06-24 11:05 new drwxrwx--- 2 flavio daemon 4096 2005-06-24 00:39 tmp

$ ls -lA /var/lib/courier/maildirs/.info/cur/ total 32 -rw-rw---- 1 flavio daemon 1268 2005-06-19 19:36 1119202571.x,S=1268:2, -rw------- 1 daemon daemon 1330 2005-06-20 13:43 1119267781.x,S=1330:2, -rw------- 1 daemon daemon 2216 2005-06-20 23:37 1119303459.x,S=2216:2, -rw------- 1 daemon daemon 1185 2005-06-21 01:01 1119308501.x,S=1185:2, -rw------- 1 daemon daemon 3289 2005-06-22 04:29 1119407359.x,S=3289:2, -rw------- 1 daemon daemon 1655 2005-06-22 08:54 1119423243.x,S=1655:2, -rw------- 1 daemon daemon 5888 2005-06-24 00:39 1119566346.x,S=5888:2,

As you can see, messages are deposited with permissions that don't allow me to read them. I changed the permissions of the first message and I can now read it, but later messages are unreadable.

The question is, what am I doing wrong?
