If you are not getting any emails sent is is probably because you are using the wrong value for your SMTP server. The server you have specified looks to be a pop server, you will need to have a regular SMTP server to connect to. You should try using your local mail server if you have one. If you are not aware of what the settings may be for this you should contact your host or admin to get you these details. The User Registration Solution Pack uses the standard PHP mail to communicate and must have access to a regular SMTP server to work.
