If you check your mail using a POP3 mail client (such as Outlook Express),
it will download and delete the mail from your WebMail inbox.

If you want to be able to download the mail using POP3 and also
leave it on the server so you can see it with WebMail, you will need
to adjust the settings in your POP3 client to tell it not to delete
mail after downloading.

For example, to configure this in Outlook Express you would go to
Tools -> Accounts -> Mail -> Properties -> Advanced
and then tick the box
'Leave a copy of message on server'

If you want to change password please login to your webmail
and then klik option -> Change Password
