How to use sendmail
 

I want to use sendmail to send an email to every someone@mycompany.com. I've read some tutorial, but I'm still confused. I don't know where to start. Can someone help me with a simple and easy to understand tutorial?
Thanks for helping.:newbie:

not a members intro. please post in appropriate forums in future - this is moved to Linux - Newbie.

sendmail is not simple or easy in general. you're much better off using a modern MTA like postfix in general. I'm not sure that your issue is actually with sendmail at all though. can you describe a bit better what you're actually trying to do and what problems you are having?

Sorry to post in an inappropriate forum. Next time, I'll pay more attention to it.

Our company has a forum using joomla, and I want to alert everyone in my company everytime someone post something in our forum by email. Can you help me? Thanks.
