Can not send out mail:

[jguy]

I'm having a problem with sendmail.
I can send messages out over the internet, but, when they get to the sender, they have the address of jguy@localhost.localdomain (the real address should be jguy@amh-web1.amhcu.org). Anyway, don't know what's causing this.

Sendmail is right "out of the box" on a Red Hat 7.2 Linux server. I haven't done a whole lot of config. I should also stress that I'm a novice at sendmail and would like any help possible with this problem. Thank you so much!!!

I'm having this same problem. Was the answer found?

Nope! We, I'm still trying to find out why. Here's a good resource to look at:

Let me know if you have any success!!!

There's a line in the /etc/sendmail.cf file that you can modify if sendmail can't automatically determine your hostname and domainname. It's towards the beginning of the file, and by default it says this:

#Dj$w.Foo.COM

Uncomment it, leave the "Dj", and replace the remainder with your hostname and domainname. Example:

Djmyhost.mydomain.com

Restart sendmail (/etc/init.d/sendmail restart) and you should be all set.
