Error sending email via Outlook express

your plusnet email address is anything@(username)

you have it seems which is invalid also are you sending the mail from your plusnet mail account and not via another isps mail server as i notice your return path was to a btopenworld address?

check your default account is set at plusnet and that your email server settings and address are correct.

Most isp will block mail from other isps some will allow it provided you have setup proper authentification in the mail server settings.

this is a anti spam feature

hope this helps somewhat

Error sending email via Outlook express

I think the problem is your incorrect PlusNet email address as mentioned above.

I send emails out using PlusNet and collect from several ISP accounts all using OE as you seem to be trying to do. I have set up an OE mail account for all my ISPs, all sending using PlusNet's outgoing mail server but I have changed the email address to the one I want eg btopenworld. I collect mails by setting OE email accounts to collect from the appropiate ISP incoming mail acccount.

An idea - are you using webmail of OE to send out your messages?

Hope this some help.
