Odoo relies on generic email aliases to fetch incoming messages.

• Reply messages of messages sent from Odoo are routed to their original discussion thread (and to the inbox of all its followers) by the catchall alias (catchall@).

• Bounced messages are routed to bounce@ in order to track them in Odoo. This is especially used in Odoo Email Marketing to opt-out invalid recipients.

• Original messages: Several business objects have their own alias to create new records in Odoo from incoming emails:

  • Sales Channel (to create Leads or Opportunities in Odoo CRM),

  • Support Channel (to create Tickets in Odoo Helpdesk),

  • Projects (to create new Tasks in Odoo Project),

  • Job Positions (to create Applicants in Odoo Recruitment),

  • etc.

Depending on your mail server, there might be several methods to fetch emails. The easiest and most recommended method is to manage one email address per Odoo alias in your mail server.

• Create the corresponding email addresses in your mail server (catchall@, bounce@, sales@, etc.).

• Set your domain name in the General Settings.

  

• If you use Odoo on-premise, create an Incoming Mail Server in Odoo for each alias. You can do it from the General Settings as well. Fill out the form according to your email provider’s settings. Leave the Actions to Perform on Incoming Mails blank. Once all the information has been filled out, click on TEST & CONFIRM.
