sendmail problems


I hate to do this but I am a newbie to linux. I recently purchased a dedicated server through ipower.com and expected something similar to what I get with their shared servers. I was surprised when what I got was a linux box with apache installed and nothing configured. It came with usr/sbin/sendmail. I found this to be standard according to what I am used to on my shared accounts. I then uploaded formmail.pl and created a webpage with a form to call the perl script. I set the delivery email address to an internal address. When I complete the form the email goes throught to the internal email with no problems. When I change the delivery email address to an external address I get the folloing errors in the /usr/local/psa/var/log/maillog file....

It appears sendmail is trying to send the email but the recieving mail server is rejecting because of the unknown sender <root@localhost.localdomain>

When I run sendmail via the command line, the maillog shows the same errors.

When I run email through horde I can send external emails with no problems. It replaces <root@localhost.localdomain> with an actual email address in the maillog. I don't think that webmail uses sendmail though does it?

How do I get sendmail to send to an external address? I searched the web and found tons of pages about setting up sendmail and creating the sendmail.cf file. I did a locate sendmail.cf and got no returns.

re: sendmail problems

The problem is that you donīt have an real dns name setup in nis or hosts file.

When sending mails to other mail servers they try to identify where your mail were sent from.
If the sns-lookup shows anything else than what your server reports, the mail will not get accepted.


So, instead of localhost.localdomain it should be an real dns name, accepted on the internet and that is connected to the ip-address your mailserver is setup on.


If you do not have an dns name, then get an free one from dyndns.org for example.

I do have a real domain name and a DNS pointing to the IP of my machine. What file do I need to edit and put this information in?

Well, easiest is to put it in the /etc/hosts file.
Example:
ipaddress dnsname.com mailhost


also, look at www.sendmail.org for more info.

Is your /etc/aliases file set up correctly? i.e;

# Basic system aliases -- these MUST be present.
mailer-daemon: postmaster
postmaster: root
root: "username"

# local aliases
"username@foo.com": "username"
"Username": "username"

(quotes to be removed)

Then run /usr/bin/newaliases. You could also shutdown and restart Sendmail
after executing the above, but the aliases are regenerated a short time
after the change - normally.
