Trouble sending emails

[annabelle]

Hi, I can't seem to send any emails.  i can receive them but when I send them this message comes up.

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was '[email protected]'. Subject 'Re: fax conformation', Account: 'Penny Wells', Server: 'smtp.ntlworld.com', Protocol: SMTP, Server Response: '550 relaying mail to online-aupairs.co.uk is not allowed', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79

I think I may have blocked my address as a sender!!

Can anyone help please. Thanks Penny

You didn't block yourself, wouldn't be able to recieve if you did.
You might have to make a new account because it isn't recognizing you as a safe account. What e-mail service are you using? What kind of computer are you on?

Did you send before? Any changes on SMTP address? But it seems your ISP has prolems far. Call them , I offer.

Hi,

Did you setup your email settings with a tick in smtp authentication is required?

sounds to me that may poss be the issue

cheers
