Send email via commandline

[pranav_j]

Hello,

I want to set a cronjob for automaticically sending an email to be IF a process XYZ is not running. The "sending mail via commandline" part is not working.

When I do "mail -s test pra...@iitb.ac.in" the prompt comes back but nothing happens.

Has anybody done this sort of thing before? Please let me know what to do.

Thanks,
Pranav

Hi,

You need a properly configured mail server for 'mail' command to work.
You can configure postfix on your system.

Another way to do this is that when a process stops, then a script can log into a remote server which has a configured mailserver. Like for CSE, we have 'mars.cse.iitb.ac.in' which can be used as a mailserver.


Thanks.
Bharat

Hi Bharat,

Thanks for the reply.

How does one login to a remote mailserver? I googled "log into remote mailserver" but didn't get exact commands. We have sandesh.ee.iitb.ac.in as EE mail server.

ssh ema...@sandesh.ee.iitb.ac.in

didn't work


Thanks,
Pranav

It seems I can't send mail to outside email ids (e.g. gmail) through mailx. Is it disabled?

No. DNS should be properly configured on the host system which I assume would already be there on 'sandesh'.
Regarding remote login [I have exchanged the RSA keys between my system and remote hosts - so no authentication is needed. Another way to do the same is to use 'expect'.] and mail send operation scripts, I can send them to you if you need them.
