Hi Whiteknight,
No its absolutely perfect mailid......
Even i tried it 4 ur mail id d same result comes...
i think when i do
nslookup smtp.cedge.in

Using /etc/hosts on: cedge2

looking up FILES
Name: smtp.cedge.in
Address: 64.xx.xx.xx

its fine right....also did u hv a look at the sendmail.cf file,probably some changes need to be done....
plzz kindly let me know hw to proceed.....

Boomer,

# "Smart" relay host (may be null)
DS[64.37.118.141]

=> You do not need [ ]

DS64.37.118.141 => do you have domain name instead of IP address

Shalom,

These are the requirements to deliver mail to a domain using modern anti-spam techniques:

1) The sending domain must be resolvable.
2) The domain of the mail server must match the sending domain.

Some optional:

3) There must be a valid reverse lookup for the sending ip address.
4) The reserve lookup information must be consistent with the domain information.


In summary, the sending location must be verifiable and consistent. Out of the box sendmail on an HP-UX system does not meet these criteria. The default domain probably is internal to your corporate network and doesn't resolve on the public Internet.

Most of this stuff is handled by your network group providing you a smtp relay for mail and making sure all the IP/DNS/reverse lookup information is consistent.

Then you need to use the DJ directive in sendmail.cf or set your domain in sendmail.mc (followed by m4 compile of sendmail tables).

Djyourdomain.com

Again yourdomain.com must be resolvable on the public internet and meet at least the top two criteria above.

Note yahoo merely accepts the mail and never delivers it. google sometimes objects but you really aren't given an indication of what the problem is. I've applied th above standards to my personal domains to decrease disk space use by spam on the servers. They are becoming much more widely used outside of big domains.

Shalom again,

Here is a test from a properly configured mail server with consistent DNS and reverse lookup.

To prevent spam, I've changed my mail from: address because real email addresses posted here get harvested by spammers.

google accepted the mail. The user was validated on the way in.

Will you get it? If it passes through the spam filters.

550 is an error that can be configured for any reason the mail administrator wants in the /etc/mail/access file. After newaliases and an m4 compile, its a rule and the mail is rejected.

Since google accepted my mail to that user, I can only surmise that one of the four rules I posted earier is being violated and that is why they are rejecting the mail.

When I attempt to send mail to google from a Linux box in my home, is part of my investmenttool.com domain but does not have reverse lookup and is actually coming from Israel's bezeqint.net ISP, google rejects it.

Why? Because the server says its part of investmenttool.com (its my Jerusalem test lab), but the mail is actually coming from bezeqint.net

So. If you have complete control of your environment, including DNS, I can provide you with step by step on how to comply with google's guidelines. Even after doing this, yahoo may still default you to the bulk mail folder.

I've only got a few hours left before the new year begins, but I'll watch the thread and help you as you request between now and 5768.

Shana Tova to all.

:-)
