help I hate sendmail - Relay denied

[Adam Noble]

Hi,

We currently have a server which I am trying to setup to send e-mails to external accounts. I am sending via our mail server another unix box. I can send a mail to my external account via this server and all is fine. I have setup my email to go via this server and that appears to be fine but I get the following error:-

sendmail -v noddy_home@yahoo.co.uk

Can anyone explain this. On the mail server I have an entry in the access file for the host.

Hi,
have you included your server in the list on your mail server ?

In our /etc/mail/sendmail.cf we have the directive:
Fw/etc/hosts

which means any machine in /etc/hosts can send mail to our mail server, who then distributes it.

[Adam Noble]

no sadly this has not done the trick.

[Ivan Ferreira]

You should add mail-noddly-europe.com and noddly-europe.com to your relay host /etc/mail/relay-domains file.

Shalom,

The server you are trying to relay mail through, idenfified usually by the DS directive in sendmail.cf needs some configuration work.

It needs to permit this host to relay, which is not the default.

Usually this is an entry in the access file.

/etc/mail/access

ip address of sender RELAY
ip address of sender OK

Example.

192.168.0.10 RELAY

This will permit relay from the specific host defined.

You may need to use the m4 command to build the access.db database.

See http://www.sendmail.org for more fun on this topic.

I like sendmail, sendmail is my friend. Its stops millions of attempted spam relay messages a year on my servers.

Hi

What is the mail server you use in unix box.Is this again a send mail server. All the mails servers whether it runs on Windows or ..nix have a configuration to use relay services. Without this the mail server becomes an open relay server and it is very dangerous.
You may need change the cfg of your relay server to add the new send mal servers details.

Thanks I have actually carried out most of this specifically the access file but I will try with the IP rather than hostname and see how we go. Thanks for your advice anyway
