How to use Webmail?

[the_king_dollars]

When I access the built-in webmail Horde, it tells me this:

Login failed because your username or password was entered incorrectly.

And some kind of error that looks like this:

Notice: Unknown(): [CLOSED] IMAP connection broken (server response) (errflg=1) in Unknown on line 0

Notice: Unknown(): [ALERT] Fatal error: /home/tkd/mail: No such file or directory in Unknown on line 0

So what's wrong?

Also, another question. Can I use another webmail program?
If I can, what do I input for the server settings? (like SMTP, IMAP, etc.)

I can't help you with the errors. I have no clue about them.

As for using other webmail clients ... what are you suggesting?

If you have your own domain name ... you can sign up for Windows Live Custom Domain, Google Hosted ... or there is another one. ( I happen to use the Google Hosted ... as it uses gmail service )

And when you sign up with them, it explains how to set up your e-mail to work with the services.
