Hello,

I'm a web-programmer, a Linux noob as of now, I'm trying to configure sendmail to work properly for testing my PHP scripts.

The script work fine, and to remove all doubts I test the mail command first, It doesn't work:
This shows no errors but I can find this on the mail log (added line breaks for better readability):



here is my etc/hosts
How can I tell sendmail that www.local.com is 127.0.0.1, it looks like it doesn't read the etc/hosts file

Please advice, thank you very much in advance.

Nabil.

The problem may be that sendmail is not logging on to akamai. akamai should (TM) tell you their requirements.

Please take a backup of any files that are changed iif you try the following steps.

Typically you need to find the .mc file that your /etc/mail/sendmail.cf is built from, modify it adding these lines (the backquote ` must be a backquote)Then, as root, process it into /etc/mail/sendmail.cf using something likeThen create /etc/mail/authinfo, readable only by root containingThen, as root, process it into /etc/mail/authinfo.db:
Restart sendmail and try again.

This time sendmail should be able to log on to akamai but they may check the from address and reject "local.com" as invalid. My blog has a partial solution to this problem -- "good enough" if it's OK for sendmail to hang for ~1 minute when it starts and every time it sends a mail!

Finally, the root account is special; I found I had to use mailx's -f option to give a fuller "From" address; sending mail from a non-root address was straightforward.

This is a "work in progress" for me; I am very interested to know what you find out and to find out how to make sendmail work while keeping the /etc/hosts entry for the local machine as localhost and localhost,localdomain

Good fortune!

Thank you for your reply.

The problem is that my machine should not go to xyz.akamai.net, I mean I'm using the domain name www.local.com as a FQDN for my server over my LAN, xyz.akamai.net is what www.local.com resolve to, in my case, I want it to resolve to 127.0.0.1, all other programs including the webserver see www.local.com as the local server but sendmail sees it as the real www.local.com !!!

as I said, it looks like sendmail is not interested in the /etc/hosts file

Please advise.

Sorry I misunderstood. Here's from Linux Home Networking

Configure the /etc/resolv.conf File

The sendmail program expects DNS to be configured correctly on the DNS server. The MX record for your domain must point to the IP address of the mail server.

The program also expects the files used by the mail server's DNS client to be configured correctly. The first one is the /etc/resolv.conf file in which there must be a domain directive that matches one of the domains the mail server is expected to handle mail for.

Finally, sendmail expects a nameserver directive that points to the IP address of the DNS server the mail server should use to get its DNS information.

For example, if the mail server is handling mail for my-site.com and the IP address of the DNS server is 192.168.1.100, there must be directives that look like this:

domain my-site.com
nameserver 192.168.1.100

Thanks again, I'll read that

Edit:
Finally worked, thank you for the link, it really helped.
