Error sending in Outlook 2007

[evenflow]

I have a domain and email set up with Register1. All has been fine for months.

This morning I can't send emails from Outlook 2007. When I do a send/receive, I get the following error:

Task '[e-mail] - Sending' reported error (0x800CCC80) : 'None of the authentication methods supported by this client are supported by your server.'

I haven't changed any settings in Outlook. Any ideas?

Contact register1 , it sounds like something has changed on the server

I had a similar issue with my provider. Nothing changed in outlook , i could recieve but not send and magically after i opened a call it magically got fixed....

I have contacted them and received several replies. I'm none the wiser, I must say...

ETA: Reg1 are telling me the most likely cause is that I need to change my SMTP setting from mail.mydomain.co.uk to something that my ISP will provide me?!

Anyone?

Logged a ticket with BT this morning, but have so far received no response at all

Haven't been able to send any emails all day. Very frustrating.

Hmm. If I check the radio button marked "Log on to incoming mail server before sending mail" and do a send/receive, I get this:

Send test e-mail message: Cannot send the message. Verify the e-mail address in your account properties. The server responded: 553 5.3.0 Spam blocked see: http://spamcop.net/bl.shtml?XX.XXX.XXX.XX

WTF?

Just looked into this for you, seems your IP has been tagged as a source of spam.

The guys have left you an explanation and some tips in the support ticket.

Let me know if you have any queries.

Any ideas why that might be?

PS - I most certainly haven't been sending spam!

Restarted the PC and now have a new IP address. Send/receive working fine.
Just need to work out why I was blacklisted. Sounds scary

9/10 on dynamic IPs its the person who had the IP before you that was spamming (virus, or open WiFi etc)

If this is just a one off, then think nothing more about it other than considering a static IP.

Thanks Jamie. I'm scanning all the machines on my network at the moment, just to be sure.

This was never something I considered using dynamic IPs, certainly something to bear in mind.

I'd also like you to pass on my thanks to your team - they answer queries so quickly!

BT Yahoo have recently changed their SMTP anti-spam policy. If you are using BT for your DSL line and sending via their SMTP servers yet quoting a non BT domain (ie: not @[e-mail] etc) then they ae blocking it. Details are on a Google search, but it's very easy to get it sorted. You log into BT Yahoo webmail and change some options that involve adding your non-BT Internet address.

A refresh of public IP only sorts it for so long before they realise and the process starts again.

Sorted this for my mum last week. Took all of 5 minutes via remote desktop...

HTH,

Roop - you the man. It was the BTYahoo settings change as you said.
I have verified my other account (the domain I hold @ Reg1) so fingers crossed it won't happen again.
Once again, thanks.

No worries. Welcome. Hope it fixes it.
