send mail upgrade

[常有慈悲心]

I have upgrade sendmail from 8.8.6 to 11.11.0 on HPUX11.00 and generated new sendmail.cf from /usr/newconfig/etc/mail/cf/cf/gen_cf.
After the new sendmial.cf be copy to /etc/mail, the users on this system can send mail to each other and to other system 's users like sohu.com,hotmail ...
But users on other mail server can't send mail to users on my mail server.The from outside will be received by my mail server for several times, and then the server will tell me that "there are too many hops, max is 25".

Hi
first of all Check the message header,
where the messages are going and from which
server it is replied.
Also check the alias file, that is it
configured properly.

I think the problem is with the alias database. Possibly some alias is pointing to the server which is vice-versa in next server.

ex:
~~~
ServerY -alias database:-
name@serverX.hp.com

ServerX -alias database:-
name@serverY.hp.com

Thanks to Srinivasan A & Gnananandhan.
I want to know how to config the alias and what the alias config file's format is.

hi,
/etc/mail/aliases file is the configuration file for aliases.
The syntax will like this.
manager: root

Here manager is the alias for user root.
After editing this file for adding you own aliases , you have to rebuild a new /etc/mail/aliases.db aliases database file with the new parameters , you have added in /etc/mail/aliases. That can be done like this.
#newaliases

(or)

#sendmail -bi

Hi,
I'm not sure about alias, may be it's a kind of dns trouble, (you check if domain name is real from incoming mail.).
To debug sendmail config, the best way is to telnet 25.
Then you have to type the right commands :
HELO
MAIL FROM:user@domain
RCPT TO:user
DATA

.
Check your logs (syslog or mailog) on the server side.

hope it may help
