"mail" program not working to mail a user working at other host.
 

there is a problem with the internet connection settings.

As a test enter the following line at a command line in your user name: echo "Hello, I work" | mail your-user-name

Hi Dave ,thanks for the reply.

So it works locally but fails remotely? That indicates a transport problem, but you are posting to this list successfully and that indicates no transport problem. Are you sure user@hostname2 was actually the address you wanted? Perhaps it just went astray. or was delayed in transit?

Dave

thanks for the reply

I do not know what is happening. I thought "mail" was a local delivery agent that passes to a "mail transport agent" (I use sendmail - running as a daemon) to deliver to other machines. If you are able to use mail to deliver directly to other machines --- hummmmm..... Let's try using mail to send to me directly.

Try: echo "Hello Dave -- this works to you, thanks, stalin.varanasi" | mail m

and let's see if that works.

Are you using "mail" to make your posts to the linuxquestions list?

later, Dave
