Hi,

I am configuring Sendmail Aliases to let system run a script after receiving a mail.

But it seems not working, message re-direction is ok, here is the details:

root: another-user --- working
root: |/script --- not working

Anybody wants to help me? thank you.

Tryi.e. use the quotation marks around the full path to the script you want to run and see if it works.
After editing /etc/mail/aliases, run "newaliases" and restart sendmail.

Regards

Thank you Bathory.

I tried this, still not working.

Here is a part of my aliases file.
-------------------------------------------
# Person who should get root's mail
#root: marc
root: yangg
yangg: "|/tmp/run.sh:"
-------------------------------------------

Messages sent to root can be forwarded to yangg, but if you address yangg nothing happens, yangg cannot receive this message either.

script run.sh is very simple: touch /tmp/aliases.tst, that's it.

I really don't have idea.

If you need to view my sendmail.mc file, please let me know..

Thank you in advance.

Edit aliases and in the line:
remove the colon ":" at the end of the script name. The line should look like this:
Also make sure that the script is executable:

Hi Bathory,


Excution permission has been granted to the script run.sh and the colon is also removed.

After that, I run newaliases, restart sendmail sucessfully. But ... no good.

Anything should I do with sendmail.mc or sendmail.cf?

Take a look at the log files /var/log/maillog, /var/log/messages or whatever other log files your distro uses to see if you find any clues why the aliases is not working.
What distro are you using btw?
I don't think you have to do anything with sendmail.mc or sendmail.cf, since normal usernames aliases work.

--------------------

Yes, normal aliases works. The Aliases seemed to be triggered, but failed in running the script. It looks like that statement "|/tmp/run.sh" was treated as an address instead of a command.

For our convinience to talk, I hereby numbered the log.

What is "Distro"? Basically, besides access file and aliases it's all default in Redhat9.

Distro is the Linux distribution you use, so you've answered it's RH 9. Anyway looking at the logs smrsh looked suspicious, so doing a little googling, I found this.
So I guess you need either to create the symlink mentioned there, or disable smrsh, in that case you need to rebuild your sendmail.cf.

Hi Bathory,

It's done!

I created a link under /etc/smrsh pointing to my script according to the following information:
-----------------------------------------------------------------
To allow the procmail program /usr/bin/procmail, use the following commands:
[root@deep] /# cd /etc/smrsh
[root@deep ]/smrsh# ln -s /usr/bin/procmail procmail

This will allow the mail and procmail programs to be run from a user's .forward file or an aliases file which uses the program syntax.
-----------------------------------------------------------------
This information is from
http://www.faqs.org/docs/securing/chap22sec182.html

But I got to switch to this link exactly from the webpage you passed to me. You have been always on the right direction, expert!!

Thank you.

I pasted all these meant to share with other people may need this.

Thank you all.

Case closed.

Thank you again Bathory!! I hope I can help people like how I was helped.

You are welcome. I'm glad you've made it.
