Pardon my english. I'm italian. I would like to put SQMail Module in a new XOOPS site here :
http://www.eulisse.com/blog/modules/sqmail/src/login.php

But i can not enter in the login such as admin or such as another user. I try to put in the login the username admin@eulisse.com and admin (without @eulisse.com) but i receive this error :

SquirrelMail version 1.4.0
By the SquirrelMail Development Team
ERROR
Unknown user or password incorrect.

I have also try to enter in the SQMAIL module (SQMail Demo) in official support site here :
http://www.guanxicrm.com/modules/sqmail/src/login.php

using for login : demo@guanxicrm.com password=demo and also username demo password demo

But i have received the same error :

SquirrelMail version 1.4.0
By the SquirrelMail Development Team
ERROR
Unknown user or password incorrect.

This night. I have also used my username in guanxicrm.com site here :
http://www.guanxicrm.com/modules/sqmail/src/login.php
login ullone@guanxicrm.com but... same error !

For me. It is not possible to login in SQMail module in my domain and in official support site. Why ?
I DO NOT UNDERSTAND !
