Problem sending Mail through MS-Outlook

By aamir_riaz999 ·
I've MS-Proxy 2.0 on Windows-NT 4.0(SP4) machine. Clients are using Windows 95 & 98 and they can't send their mails but they can receive mails. 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 ''. Subject 'Test Mail', Account: 'FDM', Server: '', Protocol: SMTP, Server Response: '550 not local host, not a gateway', Port: 25, Secure(SSL): No, Server Error:550, Error Number: 0x800CCC79"
If anyone can help me then reply.

Try Tech Q & A

You will get a better response if you post this question in the Tech Q and A section.

Sounds like whatever server you have configured in the Win95/98 mail software as the sending/outgoing SMTP server is incorrect, or is not set up to relay mail.

Are you going through the Proxy to receive email or are you bypassing it? I have a SonicWALL Firewal that I use on my network. We host our own email server for incoming mail. But I use our ISP's SMTP to send mail. I have to setup my rules and services on my firewall to allow this. It routes everything to it's appropriate places.

It sounds like to me that you just have a routing problem. I don't know much about MS Proxy but I hope that this helps you.

Problems sending E-mails

by ChrisMS In reply to Problem sending Mail thro ...

We used sometimes get similar messages on our network. We are using MS Exchange server with BT as our ISP. Most of the time we can put it down to a problem with BT's hosting, but occasionally I have found that checking the POP3 server address in outlook, & possibly changing it up 1 solves the problem.
If you are not using MS Exchange on your server, I would suggest trying it.
You do not say if Everyone gets the message displaying your E-mail as the address that could not be resolved, but ifthis is the case, I would check that your account is still active.
Hope this helps.
