1. Create a local account
|
|
|
|
|
-------------------------
|
|
|
|
|
|
|
|
|
|
Create a dedicated local user account called "vacation".
|
|
|
|
|
This user handles all potentially dangerous mail content - that is why it
|
|
|
|
|
should be a separate account.

2. Create a directory
|
|
|
|
|
---------------------
|
|
|
|
|
Create a directory, for example /var/spool/vacation, that is accessible
|
|
|
|
|
only to the "vacation" user. This is where the vacation script is supposed
|
|
|
|
|
to store its temporary files.
|
|
|
|
|
2. Create a log directory or log file
|
|
|
|
|
-------------------------------------
|
|
|
|
|
|
|
|
|
|
If you want to log to a file ($log_to_file), create a log directory or an
|
|
|
|
|
empty log file.
|
|
|
|
|
|
|
|
|
|
This file or directory needs to be writeable for the "vacation" user.

Note: If you are logging to syslog, you can skip this step.

|

Copy the vacation.pl file to the directory you created above:
|
|
|
|
|
|
|
|
|
|
$ cp vacation.pl <HOME>/vacation.pl
|
|
|
|
|
$ chown -R vacation:vacation <HOME>
|
|
|
|
|
3. Install vacation.pl
|
|
|
|
|
----------------------
|
|
|
|
|
|
|
|
|
|
Create a directory /usr/lib/postfixadmin/ and copy the vacation.pl file to it:
|
|
|
|
|
|
|
|
|
|
$ mkdir /usr/lib/postfixadmin
|
|
|
|
|
$ cp vacation.pl /usr/lib/postfixadmin/vacation.pl
|
|

|
|
$ chown -R root:vacation /usr/lib/postfixadmin

|
|
$ chmod 750 /usr/lib/postfixadmin/ /usr/lib/postfixadmin/vacation.pl
|
|
|
|
|
|
|

Which will then look something like:
