 Posted: Sun Feb 25, 2007 9:07 am Post subject: [WORKAROUND] Mail permissions not right (not solved yet) |
 |
|
I 'm having a problem with my procmail setting wrong permissions. I have a workaround which I want to run as soon as procmail has run.
The command which needs to be run is something like CHMOD -R 777 ...
How do I do this?
Further down it's adviced to use UMASK. But how to do that

You do not want to do that. I would suggest reading up on umask instead.

| Thanks. I'll do at. What I quickly read is that the new files will be created and then when a user "touches" them they can open them. So I'll have to figure out how fdisk/procmail is to be used running with UMASK |

| I've tried adding umask to the command in my /etc/ini.t/fetchmail where I added procmail but that doesn't work. So I have to figure out where it will work. |

from the procmailrc man page:
| Quote: |
UMASK
The name says it all (if it doesnât, then forget about this
one  . Anything assigned to UMASK is taken as an octal
number. If not specified, the umask defaults to 077. If
the umask permits o+x, all the mailboxes procmail delivers
to directly will receive an o+x mode change. This can be
used to check if new mail arrived.
|
So, just set UMASK to whatever you want in your /etc/procmailrc or ~/.procmailrc
Anyway, why do you want a mailbox with group and/or other permissions?

This is as a workaround
When my mail is fetched with fetchmail (starting at startup) it's filtered by procmail. See my /etc/init.d/fetchmail
| Code: | start() {
checkconfig || return 1
ebegin "Starting fetchmail"
start-stop-daemon --start --quiet --exec /usr/bin/fetchmail \
-- -d ${polling_period} -f /etc/fetchmailrc \
-m "/usr/bin/procmail -d %T"
eend ${?}
} |
Then /etc/procmail says:
| Code: | DROPPRIVS=y
SHELL=/bin/sh
INCLUDERC=/storage/mail/procmailrcs/ekoster
# Use maildir-style mailbox in user's home directory
MAILDIR_ROOT=/root/.maildir/
#MAILDIR_EKOSTER=/home/ekoster/.maildir/
#
## Begin recipes
#
:0
* ^To:.*mobile\@domain\.net
$MAILDIR_ROOT |
The included file will have the same TO filter for a that user. The mail folder at moment reside in the home dir but when it works its to move to /storage/mail/boxes/$USER.
Now when mail is filtered I can't open it as a user. The permissions aren't right. I discovered that the chmod makes them readable. It's dirty, but I don't know how to solve it. I know it should be possible. I could go back using different pop accounts and fetchmails but I want the catch-all for type errors and then I can make the aliasses internal instead of going to the ISP every time. And there are to be two domains.
Adding UMASK=777 to the to of my procmailrc under SHELL didn't do the trick, oeps, thats the wrong permissions. I figured out. It will work with 000. So my workaround works. |

UMASK of 777 would block all permissions (equivalent to chmod 000 file). UMASK of 000 will open all permissions (equivalent of chmod 777 file). I must restate that it is a very bad idea to chmod files to 777.
Also, you don't need to modify the init script for fetchmail to specify procmail as your MDA. You can specify that in the /etc/fetchmailrcor ~/.fetchmailrc.
Also, how is any mail getting to /storage/mail/boxes/$USER if you have MAILDIR_ROOT=/root/.maildir/ set? I think you are making this much more complicated than it needs to be.

| Thats the location where I would like the boxes. But I can't get that working. I first going to get the other things working. Like the permissions without a workaround. I don't want 777 but until I find the right way this will work. |

Just change the UMASK. If you want perms of 750, UMASK=027. If you want perms of 660, UMASK=117, etc. You don't need 777.
