I think that the problem is on MX record on your DNS, because : 1) you can send internal e-mail On snoopy, everything works fine. But not in internal domain

2) you can send external e-mail( this e-mail is sent from sundar on esaravana.com) Right now I have only these two machines and they are not connected to outside world. I want to setup everything, configure the firewall and put it on the internet

the user Sundar is on the snoopy (right?) and when you try to send an e- mail to sundar@esaravana.com from the same user, the DNS server doesn't known who is the Mail Exchanger (MX).

Please try - nslookup - nslookup

...

set querytype=mx esaravana.com -----> Now you should see: esaravana.com preference = 10, mail exchanger = snoopy.esaravana.com

Hi

...

I think that the domain in sendmail files isn't correct Is your hostname "snoopy"?

Yes and it's my mail server, web server, gateway

...

----> Try to send a mail from sundar@snoopy to sundar@snoopy.

Successful

...

------> View /etc/sendmail.cw, where you find the domain that the sendmail manages. Here there must be "snoopy", "snoopy.esaravana.com" and "esaravana.com". I did not see this file in my system. So I created one. ---------> How you have created the user sundar? It must be inserted into /etc/aliases in the following format sundar: local_user. , then you must launch the command "newaliases"

I modified /etc/aliases with text editor(would it make any difference) and added sundar: sundar

...

Now I am able to send and receive in the local(snoopy) machine. But if I go to my Solaris(FQNM:charlie.esaravana.com; also my DNS for domain esaravana.com) I get the same error ######################################################## cliebt side message Response: 501 5.1.8 .. Domain of sender address sundar@esaravanana.com exist.

Hello,

I finally managed to configure my mail server at home on my gateway with sendmail/qpopper. I am able to receive my mail from default root(root@snoopy) account to any of my other local accounts(e.g Sundar@eSaravana.com). But when I try to send mail from any of my local accounts(Sundar@eSaravana.com) to itself(Sundar@eSaravana.com) -- I have just created only one account -- I get following error message

Sending failed: a SMTP error occurred. Command: MAIL. Response: 501 5.1.8 .. Domain of sender address sundar@esaravanana.com exist.

My local DNS server runs on another machine and the domain is --esaravana.com

And my sendmail configuration is as follows snoopy:~ # sendmail -d0.1 Version 8.11.2 Compiled with: LDAPMAP MAP_REGEX LOG MATCHGECOS MIME7TO8 MIME8TO7 NAMED_BIND NETINET NETINET6 NETUNIX NEWDB NIS NISPLUS QUEUE SCANF SMTP TCPWRAPPERS USERDB

============ SYSTEM IDENTITY (after readcf) ============ (short domain name) $w = snoopy (canonical domain name) $j = snoopy.esaravana.com (subdomain name) $m = esaravana.com (node name) $k = snoopy ========================================================

Recipient names must be specified

Any help! Sundar
