[17.0] mail_tracking: Recipient email addresses are incorrectly displayed in tracking

[melissalateb]

Module

mail_tracking

Describe the bug

When sending an email to multiple recipients, the tracking system shows the recipient addresses in a broken format. Instead of displaying proper email addresses, the output shows a list of characters separated by commas, as if each letter was treated as a separate item.

This issue only happens when at least one recipient is added in Cc or Bcc (using the mail_composer_cc_bcc module). Without Cc/Bcc, tracking works correctly.

To Reproduce

Affected versions: Tested on Odoo 17.0 (may affect other versions too)

Steps to reproduce:

1. Install module mail_composer_cc_bcc
2. Send email from chatter
3. Add multiple recipients in the "To", "CC", "BCC" fields
4. Send the email
5. The recipient field will show something like l, a, t, e, b, @, ... instead of full email addresses

Expected behavior Recipient email addresses should be displayed correctly, like: [email protected], [email protected]
