Try to rework this solution for your friend's ISP:
You may get the error message
* 'The server does not support a SSL connection. Account; pop.tiscali.co.uk Server smtp.tiscali.co.uk.' Protocol SMTP, server response '250 HELP' Port; 25, Secure (SSL) Yes, Server Error 250, error number 0x800CCC7D.'
* "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 'The monthly collection', Account: 'Test (Tiscali)', Server: 'smtp.xxxxxxx.xxx', Protocol: SMTP, Server Response: '550 relaying to prohibited by administrator', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
This problem happens because your version of Outlook Express is set up to use Secure Socket Layer (SSL), which Tiscali does not use.
To fix this problem:
* Open Outlook Express, and click Tools
* Then click on Accounts
* Then click on your Tiscali connection and click Properties
* Then click Advanced
* On this screen remove the checks from the boxes This server requires a secure connection for both Outgoing mail (SMTP) and Incoming mail (POP3).
* Bear in mind that you should be using a dial-up connection number prefixed with 1470 and that the outgoing mail server is smtp.tiscali.co.uk
