Sendmail 550 5.7.1 Relay denied problem

[poonwaikuen]

Dear all,

I have install sendmail in Redhat 8. I can use it to send mail within my lan but
I cannot send or receive my mail from outside (e.g. yahoo mail or gmail mail).

While I send email outside, I receive an error of "550 5.7.1 Relay denied".

Can you tell me, what wrong with my sendmail setting?

Thanks!

Alex

Supplementary Information :

I am using dynamic IP and have hostname registered from dyndns.com.
In addition, I have set my mx record along with this hostname.

I just setup my sendmail server last night and I don't think my email server
was in RBL (Relay black list).

How can I solve the problem?

Thanks

Alex

[jledhead]

can you post a bounced transaction from your mail log and maybe a sendmail config

<Above is most of my sendmail.cf>

1. I have add my domain after Cwlocalhost
2. I have let my sendmail listen to 0.0.0.0

Hope this can help you in analysis! Thanks!

According to this article
'Relaying Denied' Error while trying to send email

It's not a bug:

Many smtp servers use some sort of protection against email spamming.  This only allows trusted users or computers to send email via the server....

Check this one too
Relaying Denied/Allowed (in sendmail 8.8/8.9-8.12)

and try trouble shooting sendmail
like this
Quick HOWTO : Ch21 : Configuring Linux Mail Servers - Linux Home Networking

What's the error message ?
What's your /var/log/maillog file contents ?

Hope anyone can tell me what wrong in my sendmail configuration. Thanks!

Addition information

My Domain name is "mydomain.selfip.com" and my MX hostname is

"mx.mailserver.com" which is different from my domain name.

I want to use mail.mydomain.selfip.com as my MX hostname but dyndns.com
do not allowed. Dyndns.com suggest to use "mx.mailserver.com". Is that OK?

When I ping mx.mailserver.com, it cannot resolve to my domain name's IP.
It is rather strange!
