Hi
My landlord at my secondary residence has changed ISP from BT Broadband to Sky Broadband. I am now finding that sending email through relay.plus.net now fails with an undeliverable, the message in which is 550 relay not permitted
I can receive OK.
The Outlook 2003 test account settings finds the SMTP server but fails to send the test email, asking to verify the email addess field.
Is this a particular problem with relay.plus.net not accepting emails from the Sky network, I wonder. Like I said it worked fine from BT and also O2 broadband, with the SMTP server set to not requiring authentication (though it will not accept the authentication if I do tick that checkbox)

Hi Stuart,
As you're on Sky Broadband you will only be able to use our relay server if you set authentication to yes, and this will only work if you are on a subscription account with us. If we didn't have these measures in place our mail servers would be 'open relays' and very very easy for abuse by spammers.

Thanks Chris. Any reason it works OK with O2 and BT Broadband?

BT Broadband works because of the Plusnet PAYG users on the RIN trial. We get BT IP addresses so the BT ranges had to be allowed.
