RE: ExChSrv sends multiple copies of emails to users via POP3

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi,

Thanks for updates.

I am sorry this issue should be relate to ISP side, you could ask your ISP
to see if they can set a smarthost for you. But from your description, it
seems you have forward all your unresolved emails to your ISP smarthost,
this should be smarthost for you can use.

Please also understand that you need to contact your ISP to see if they
offer smarthost for you to send and receive emails. Is there any additional
authentication for smarthost.

Smarthost is also a mail server which host on ISP, it have been configured
for mail relay, it is a special mail server. All need to be configured on
ISP side, you only need to know how to authentication with that mail server.

If you use DNS to route emails, make sure that you have a MX records on
internet, so that it will make your internet emails sending without any
problem.

Thanks for understanding here. I am glad to be of help.




Best regards,
