You need to configure the Incoming mails for creating tasks, task updates, etc while the Outgoing mail for receiving notifications. The following pages will help you set that up.
Celoxis requires a dedicated email account to work for which your system administrator needs to create a mail account on the mail server. If you use an ISP then, you can create an account with your ISP provider.
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.
