Problem Sending email

I just cloned a Red Hot 8 ( production) machine to have an development enviremont.

Every thing seems to work fine except 'email'.

I use the command:

mail my_email@address

On the production machine the email arrives inmmediately.
On the cloned one (Development machine) it doesn't work.

I've very little experience on linux but I have to solve this problem, for my boss, to test some php scripts which send mail.

Can somebody help and tell me which changes are needed on the cloned machine to get 'mail' working. Or any thing else which can help

Thanks in advance

Does DNS work fine, too? (I. e., have you set a new hostname on the clone?) Do you get any useful errors if you run mail with the -v flag and/or in /var/log/mail etc.?

DNS works fine too and there are not logs on /var/log or /var/log/mail.

Running mail with the -v flag: it gives a "(will queue)" message.
I do not receive the mail.

the full line is:
250 2.1.5 <myemail@address.com>... Recipient ok (will queue)

Thanks again

Hello,

After some changes and a reboot, I do not get any more the message ""(will queue)".

but after running email with the -v flag again I get:

250-www.prod_domain.com Hello www.prod_domain.com[127.0.0.1], pleased to meet you

The old production-machine domain name remains somewhere present in some configuration file, and perhaps because of this the mails are not send. Any idea where?

In etc/sysconfig/network I changed the Hostname entry from old production-machine domain (www.prod_domain.com) to localhost
HOSTNAME=localhost

but it doesn't help.

Any ideas will be greatly appreciated
Thanks in advance

Thanks for all the help.

I think the problem to get mail send is the SMTP configuration which is using DNS to send the mails.

How can be SMTP configurated to get all emails forwarded to a specific mail server?

Thanks

Add this line to your sendmail.cf:(replace mail.foobar.com with your mail server) and restart sendmail. I'm not sure whether that change is sufficient; let's hope it is. Also update the old hostname if necessary.

Thanks any way , but the emails remain queued

What exactly did you change? Any traces of the old hostname still around in /etc (and /usr/local/etc, if you've got anything there)? Any log messages from sendmail?

Sorry for asking questions all the time, but it's hard to read your machine's mind.

It works now.


Thanks a lot.

I inserted DSsmtp:mailserver on sendmail.cf and changed the localhost name: localhost gives problems.

best regards
