Mailboxes
Export mailbox credentials
How to download SMTP/IMAP credentials for many mailboxes at once, including why the link is short-lived.
How to export
Dashboard: Mailboxes → export. API: the mailboxes export endpoint. You get a file with addresses and passwords.
The download link expires on purpose. A permanent URL full of SMTP passwords is an incident waiting to be copied into Slack.
