I don't think the problem is anything to do with the ISP, just the setup on the local IIS server. I've just tested the suggested procedure successfully. I originally got the same "unable to relay" messages - my IIS server was not set up to relay by default. In the SMTP server properties there's an "Access" tab and at the bottom, the relay restrictions. You need to grant permission to relay for the domain you want to send emails from.
I have to point out though that if you try and send a lot of email through an SMTP server on your PC, it still all goes through your Internet connection and your ISP may notice this and suspect you of spamming, and possibly cancel your access. Maek sure you are not going to be in breach of their acceptable use policy. > >> Thanks so much for introducing me "How To Test Windows > >> 2000 IIS SMTP Services Manually" I use the steps by this article > >> to check the work of SMTP in my IIS and find question.
