Now if two mails come simultaneously. It is overwriting the /tmp/mail ,
and thus my script gets confused and didn't work.
OK - there are a number of solutions which don't require timers.
Simplest is to use a lockfile, so there will only be one instance of
your script running at one time, for example:
:0 : script.lock
{
:0 c:
/tmp/$TIME
:0 c
| EX_SCRIPT -w ........$WHOFROM ............../tmp/$TIME .........
}
Other mails will wait to be processed whilst the lockfile 'script.lock'
is held by the recipe.
Alternatively, rather than using a filename based on the time, use a
filename based on the process ID of procmail:
FILENAME=/tmp/scriptmail-$$
:0 c
$FILENAME
:0 c
| EX_SCRIPT....$FILENAME
No other process will have that process id whilst procmail is running.
Hope that helps,
Martin
