I have a clients PC which uses Outlook Express for email. We can receive email fine. When we try to send it comes up with the following error:
The connection to the server has failed. Account:
'mail.tadaust.org.au', Server: 'smtp.tadaust.org.au', Protocol: SMTP,
Port: 25, Secure(SSL): No, Socket Error: 10013, Error Number: 0x800CCC0E
Their ISP is tadaust.org.au
Tadaust have said their email system is fine. In fact they said they do not support Outlook Express and we should use their webmail. The email system used to work fine up until recently.
I have put the PC on my Internet service and set mail.bigpond.com in the outgoing mail server and it worked fine.
But when we use his system and use smtp.tadaust.org.au it will not send email.
Can anyone help?
