Need help with SENDMAIL!!!!!

lil'loo · 06-26-2001, 09:59 AM

I am running RedHAt 6.2 and using a using the SENDMAIL but when I test it out it, shows the incorrect email addy. Instead of "jdoe@mybusiness.com", it reads my address as "jdoe@mycomputer.mybusiness.com" . What can I do to fix this? Please help!

Check your /etc/hosts file.

This is where the address is coming from.

When you send mail from the command line? Or in a tool? If its being sent from a tool just adjust your from address... If its from the command line then you need to get sendmail to rewrite your outgoing address.

/etc/hosts is only used for name lookups. You could change your machine name by editing /etc/hostname but that won't solve the problem just change it a little..

I'm pretty sure he meant sendmail as in the sendmail server daemon. At least that was what I was advising him about. When you see the address:

joeblow@mycomputer.mydomain.com

usually, the domain is being pulled from /etc/hosts, or at least, that's my understanding.

My understanding is that /etc/hosts is only used for the lookup of ip address. The hostname itself is set in /etc/HOSTNAME (on my Slackware boxes) which holds something like machineName.domainName.parentDomain.net, this is read at boot time and used in a call to hostname in one of the scripts that looks something like

Code:

/bin/hostname `cat /etc/HOSTNAME | cut -f1 -d .`

Sendmail constructs the from address using the hostname and the username. There would be nothing to stop you (although it would break a few things!) from having no mention of your IP address in /etc/hosts but your hostname itself would still be set.

cheers.

You can always hack at your sendmail.cf file.

Remove the $w from this line and hardcode in your domain name.

Code:

# my official domain name
# ... define this only if sendmail cannot automatically determine your domain
#Dj$w.mydomainname.COM
Djmydomainname.COM
