Check to see if you can resolve the domain name (nslookup hotmail.com). It sounds like it may be a DNS problem. If you can not resolve the domain name you either have to put the domain in the hosts file or disable DNS on the system.

this server is server of DNS
there are no problems of DNS:

nms1 # nslookup hotmail.com
Using /etc/hosts on: nms1

looking up FILES
Trying DNS
Non-authoritative answer:
Name: hotmail.com
Addresses: 64.4.52.7, 64.4.53.7, 64.4.54.7
*********************************************
nms1 # nslookup astalavista.net
Using /etc/hosts on: nms1

looking up FILES
Trying DNS
Name: astalavista.net
Address: 212.80.184.50

nms1 #

Is there any good info in /var/adm/syslog/mail.log about these emails?? Also attempt telneting to hotmail.com 25 and sending an email directly from their server. They may not accept your mail because they can not resolve your domain name.

Hi,

/etc/mail/sendmail.cf should be configured to send external mail. Check for DS flag in sendmail.cf and put the entry over there for external mail resolver
Restart your sendmail daemon by /sbin/init.d/sendmail stop followed by /sbin/init.d/sendmail start

GoodLuck..

DS

the problem resulve but I cannot be used that server of realy so that they do not belong to us and the mail not so that they do not belong to us and the mail they do not leave to Internet

I still think it may be domain resolution on the hotmail side. I imagine you are sending mail out as user@hostname.domain.com. hostname.domain.com can not be resolved. Try chaning DM macro in /etc/mail/sendmail.cf to DMdomain.com (whatever your domain is) and restart sendmail.
