Sending email via a LAN connection

By hilton.grobler ·
Hi all.
Our office is running Windows Server 2003 and we are having problems sending email through the LAN. However, when the employees send through the same account at home, they don't have any problem. I connected a laptop to the LAN but did not set it up as a user on the network and was able to send & receive mail,so the connection should be fine. What application permissions are related to email sending & what other things can I check?
Thank you,
Hilton

Sending mail through Exchange or Outlook or something else?

Here are some things to consider:
Most ISPs do not want to be used as a relay for people who are not their customers - rightfully so. But if you are their customer at home and try to use your home ISP mail system they don't like the IP address you are using and they do not relay your mail. So POP3 would work but SMTP would not. Most broadband providers have a web interface you can use at work or outside their network in general.
The other thing is I highly suggest blocking outbound SMTP traffic from anything other than your corporate mail server. That will prevent infected computers sending their own SMTP mail from the company IP address which could be bad for business.

I guess you have a policy against this or your mail server is not configured properly.

To get more help you need to precise the mail server, the message you get back and so on.

All client laptops are using Outlook 2003. Outlook gives this error:
"Your message did not reach some or all of the intended recipients:
Subject:
Sent:
The following recipient(s) could not be reached: 'name' on 'date & time'
554 <email address of recipient>:relay access denied"
The sever is not specifically set up in Server roles as a mail server, the dial-up connection is just shared.

The 554 error is that the user didn't have the rights to send through this server.
It may just be that you need to check the "outgoing server needs confirmation" or something like that... It under account configuration-->advanced-->outgoing config.
If that is not working you'll have to check the configuration of the server and give needed access to the users.

I think its the permissions. I sent an email directly from the server(as admin) and that works,with the same email account settings.
Do you have ideas on which application permissions I have to set? All clients are part of the USERS group.
