Problem sending mail (MS-Proxy Client)

By aamir_riaz999 ·
I have MS-Proxy Server 2.0 on my Windows NT 4.0(SP4) machine. I am using Windows 98 and Windows 95 on Client Side. I am also using MS-Outlook Express 5.0 on the Cleint machine for mailing. I can receive mails but I can not send mail with Outlook Express. An error generates...

"The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'aamir_riaz999@yahoo.com'. Subject 'Test Mail', Account: 'Aamir', Server: 'fsg6.fascom.com', Protocol: SMTP, Server Response: '550 not local host yahoo.com, not a gateway', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79"

Only Server can send and receive mails any other windows 95/98 clients can not send mails but theycan receive their mails.
I am using MS-Proxy Client on Client machine. Please if you can handle this problem then reply me as soon as possible.

Problem sending mail (MS-Proxy Client)

Do you have a rotocol definition for the SMTP and POP3 protocols in your MSProxy Service settings? If yes, make sure that appropriate permissions are set. Also, make sure that you do not have the WEB based SMTP services installed with your IIS4 service (the underlay for Proxy 2).
Log on at the servers console, go start/programs/PROXY SERVER Menu and the Microsoft Management console. Go to the Winsock Proxy, go properties, check the Permissions tab, drop down the box Protocol and make sure that the Grant Access to box has all the users you want to allow. Alternatively, disble the Access control (NOT RECOMENDED).
I hope this helps. If you need more info, I'll be happy to assist you further

I will give you a hand with this.
What is your proxy server DNS name? (your server should have a name, something like proxy.mydomain.com) ? Is not by any chance fsg6.fascom.com?
Make sure that when using outlook express, if WINSOCKS Proxy client is installed, the Internet Explorer menu item /Tools/Options/Connections/Lan Settings do not have Autodetect and Use Proxy enabled.
Make Sure that When you have installed IIS4 from the Option Pack, the SMTP service was not installed aswell!
As soon as you find out what is your domain name, I'll be able to help further.

Radu

My impression at the moment is that you are running an SMTP local queue on your Proxy server. This will explain why your clients will receive this error message. Please confirm. What happens when you try to retrieve POP3 mail from a remote account from oane of the clients?
PS: Make sure that you are not using the WEB Proxy as well on these clients, only WINSOCKS...

Problem sending mail (MS-Proxy Client)

configure access control permissions on the Proxy Server computer to enable internal users to exchange e-mail messages with Internet users. Create a new protocol definition named SMTP (server) that uses inbound TCP port 25, and grant access to the Everyone group for the SMTP (server) and predefined SMTP (client) protocols

To send and receive e-mail messages, each internal Microsoft Exchange Server user communicates only with the local Microsoft Exchange Server computer. No external e-mail clients will access the local Microsoft Exchange Server computer. Therefore, Proxy Server must be configured to allow only inbound and outbound connections to TCP port 25, which is used for SMTP. The SMTP (client) protocol that uses outbound TCP port 25 is predefined on Proxy Server. Granting access to Everyone enables the local Microsoft Exchange Server computer to send e-mail messages to Internet hosts. To enable inbound connections to TCP port 25, you must create a new protocol definition that uses inbound TCP port 25 and grant access to Everyone for that protocol. Additionally, you must bind Microsoft Exchange Server to the Proxy Server computer's TCP port 25 by creating a Wspcfg.ini file on the Microsoft Exchange Server computer.

This sounds like a Winsock Proxy configuration problem. You need to both install the Proxy Client and enable outbound access control through your Winsock Proxy Service.

As a quick check to see if it is this enable USERS or EVERYONE Unlimited access to all outbound WinSock protocols - If you go to the properties for the Winsock Proxy Service and check the Protocols Tabs you should notice that SMTP (Client)is already defined and configured, go to the Permissions Tab and enable access control and add a group/user to the list - stop and restart the services and check that it works.

Question : Did you delete the account for IUS_Computername ?? If so you need to reinstall and configure that username again. The password for that username will have to be resynched and permissions given back to that user.

<sitting in corner withdunce hat on> I made the same mistake before. Thus the only way I would know to ask that.

If you need further assistance email me.
