This change allows the user to configure both IMAP and SMTP for an email inbox. IMAP enables the user to see emails in Chatwoot. And user can use SMTP to reply to an email conversation.
Users can use the default settings to send and receive emails for email inboxes if both IMAP and SMTP are disabled.
