Hi all,
Actually I had framed the question wrong in a jiffy.........thank you for the answers..
The problem i have observed with most of the mail servers in a corporate network is that there seems to be no authentication on the relay mail server........
I have observed that although the servers in the internal network of a corporate org have proper SMTP auth means, the relays or gateways for external mail delivery do not seem to authenticate the user.
On such n/w's I'am able to send mail from xyz@copstop.com to abc@copstop.com using low level SMTP chat from home by telnet to port 25 to one of copstop.com's relay servers facing the internet. Where'as i'am not either of the two.
The mail received by abc looks original but shows
from : xyz@copstop.com to: <> undisclosed recipients
in the header and logs.
Is there a way out where I can stop
mail from: xyz@copstop.com
only when the relay server is accepting mails from other servers.(incoming)
The gateway is using sendmail as an MTA.
I would be happy to give any clarifications needed.
Note : the internal mail servers consist of exchange, sendmail servers and lotus dominos....the auth means are different. the decentralization has been done coz each unit is different entity in itself.
bye rgds
