Thanks

Just because a command works for someone else, doesn't mean it'll work for you - for example, do you have a mail server setup?

If you give more details on exactly what commands you've tried and how they've failed, someone may be able to help resolve the issues.

Setting up command line email is more complex than one might expect; it requires several different parts configured to work together.

This is a good overview: https://www.linuxtopia.org/HowToGuid...il_intro1.html

A web search for "configure command line email linux" will turn up a number of tutorials.

Personally, I recommend Mutt as a mail client.

thanks I tried mutt, but i got an issue SASL authentication failed , i don't understand it, also google din't give me a solution

sending a mail from a linux box requires some work/configuration. Without that you will not be able to send mail at all.
also see post #2 and: http://catb.org/~esr/faqs/smart-ques...html#beprecise

If you post the exact errors, messages, and commands you're entering, we might be able to help. So far, you've given us one generic message, without telling us how you configured MUTT. You also don't say what mail system you're trying to connect TO, and when you said in your first post "...all failed like mail -s subject mail , mailx mail", that also doesn't tell us anything.

We can try to help, but we can't without knowing what you've done, tried, and what you're seeing.

thanks for help i appreciate that, i'm totally new with linux, sorry for short info that i gave, so on my vm i'm using centos 8 machine, and i'm trying to send mail to post.cz , it is something for study to understand how is going to send mail via linux, so i have used mutt as in this videohttps://www.youtube.com/watch?v=tv8jSCqRmUY with this configuration https://www.thegeekdiary.com/how-to-...n-centos-rhel/ but it gave me an error that SASL authentication failed that is after clicking y to send the mail. also I have tried mail -s subj "receiver mail" that didn't gave me any error but i didn't receive the mail so sure that the command didn't word as normal, and the same issue with mailx with the same syntax , that is all. thanks

most probably the configuration you made is incorrect (or just mistyped something?). Without details hard to say anything.

Can you show us exact commands that you tried?
And what is the exact failure message?

On my RHEL/CentOS machine, this works:

If that does not work for you then your configuration is incorrect.
In that case, what did you change and what is the exact failure message?
