You need to configure the Incoming and Outgoing mail settings for your notifications, task updates to work. The following pages will help you set that up.
Celoxis requires a dedicated email account to work. So, you need to ask your system administrator to create a mail account on your mail server. If you use an ISP and don't have your own email server, you can create an account with your ISP.
We recommend the mail-user-name as 'celoxis'. Celoxis will read and send emails using this email account just like you do from your email client.
Once you create the email account, you now have to setup Celoxis with this account.
