hi i have a project in server postfix i want to create a script that make sever to send an email in time precis
help meee plzzzz !!

Perform a search with your favorite engine on these terms, separately: "postfix sendmail compatibility" and "crontab"

witout using cronjob
i want to ask if i can this script in the postfix ???

I am not aware of Postfix having a sense of time. It is a set of daemon processes that are orchestrated by the queue manager daemon which handles incoming mail and routes them. Aside from that, Postfix does not generate mail, except for automated daemon messages like failed delivery notice. You would need a separate script to compose the messages.

If this would be possible with Postfix alone, it would be a relatively obscure feature. The Postfix site has extensive documentation and contains pages upon pages of description of features and flags. You might want to see if it provides any hits.

can you give me this separate scipt in order to compose messages ?? because i never did a script plz help me because my periode of my project will finish soon

Saying your project period ends soon gives me the impression that this is a student project, which are discouraged on LQ. While many of us will help with them, you need to what you have been trying and explain what it is that you are having trouble with. The important thing is to learn and understand how things work, not to be given an answer to submit which won't work once you finish school.

Here are some links to scripts and tutorials about how to send mail:

http://www.cyberciti.biz/faq/sending...l-mail-script/
http://www.perlfect.com/articles/sendmail.shtml

The first example is from the command line and you could write a small bash script to call the function. It is really deceptively simple. The second and third example, show how to perform the same function using Perl. The choice of language is really immaterial, as they call call /usr/bin/sendmail. Each of these will show you examples of how to solve the problem. Postfix provides a sendmail function.

As I stated earlier, I don't know of a way to get Postfix to perform the timing function. This is the realm of Cron. Attempting to use Postfix for this function would also be against the Linux philosophies of do one thing and do it well and designing your programs to be read from and provide output to another program. Cron, on the other hand knows timing and that is it's function, which it does well. Cron is designed to call a script on a periodic basis. It is the perfect tool for the job.

salut
je veux savoir comment programmer un script qui permet d'envoyer un message (sous debian (postfix) )dans un temps precis
j'ai deja poser cette question en anglais mais peut etre le problematique n'etait pas poser en clair
en attendant d'une reponse merci d'avance

Asking the same question in another language is not likely to help you on LQ, as this is an English-language forum.

yes I know but I'm from morocco .English is our second language for that reason we have some problems to explain this project
so i try to understand you but plz give me answer because i need it

my question in english:
I want to know how to program a script that sends a message (debian (postfix)) in a precise time

If you mean you want to send a msg at(!) a precise time automatically, the tool you would use is 'cron', http://adminschoice.com/crontab-quic...Crontab%20file. This is the default scheduler for automatically running a process at a given time.
You can then write a shell script to be called by cron.

HTH

I created this very simple script:
I can then use it by piping the output of a command into it:

thanks ! But i wonder if it is possible to create script in postfix without using a cron !?
For (16pide) your script is based to a cron or directly in postfix and where exactly we can put it ?
