Outlook Express send mail issue

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?

Hi mbelletty

It seems to be a SSL port number issue of the outgoing server smtp.tadaust.org.au.

For a secure outgoing SMTP connection, normally it should not be port 25, you may try port 465.

Hope it helps,

I am not wanting a secure port it should be just a basic Outlook Express POP3 set-up.
I have also downloaded Incredimail to see if that works, but still nothing.

I may have to reinstall Windows XP to make sure there is no malware blocking it or somethi8ng like that!

If so, you should uncheck (disable) the SSL option.

Yeh sorry, I did tick that at one stage just to see if that was the issue.  I have unchecked it and still no go

In most cases, you also need to check an option to allow SMTP to use the same authentication settings of POP3. Please double check this as well.

I can ping both mail.tadaust.org.au and smtp.tadaust.org.au from the PC when I am dialed into their connection, but for some reason just can not send mail.
I have just reinstalled the PC, hence totally clean system.  Still can not send mail.
Also tried ticking outgoing mail server requires authentication and entered client dial-up login details for their account.  Still nothing.  I can only presume this is an ISP issue, but then wouldn't all of their clients have this issue?

When I use my Bigpond account to send mail, it sends beautifully!

I have just set up the clients email account on a laptop of mine and used his dial-up connection to connect and send/receive email.  the exact same thing happened.  I could nreceive mail from my clients account but I could not send mail using his email account and dial-up account.

i can only presume that this is an issue with the ISP????

This issue was resolved after we found that the ISP had put a block on the email address for spam email purposes.

We had to contact the ISP to get this removed after re-installing the PC due to viruses
