The term "sorcerer’s apprentice mode" is defined as a bug in a protocol
where, under some circumstances, the receipt of a message causes
multiple messages to be sent, each of which, when received, triggers the
same bug. - RFC3834

Add bounced emails to the conversation thread.
Fix Gmail bounce detection by checking the X-Failed-Recipients header.
Currently, bounced emails are rejected as auto-replies, which causes
support agents to miss important delivery failure context. This PR
ensures bounced messages are correctly added to the thread, preserving
visibility for the support team.
In Chatwoot, we rely on the Content-ID for inline attachments to replace
the link with the uploaded attachment URL. Our expectation was that only
images would be inline, while other attachments would not. However,
email clients like Apple Mail (sigh) allow users to send inline
attachments that are not images, and these attachments often lack a
Content-ID. This creates significant issues in rendering.
I investigated how other email clients handle this scenario. When
viewing the same email (sent from Apple Mail) in Gmail, only one image
appears—and it’s treated as an attachment, not inline. This happens
because both attachments are the same image, and Apple Mail only sends
one copy. See the screenshot below.

A good fix for this would be to check if the Content-ID is missing and
then upload the file as a regular attachment. However, the Mail gem (for
some reason) automatically adds a default Content-ID to inline parts. I
need to dig into the source code to understand why this happens.
For now, I’ve implemented a check to treat non-image attachments as
regular attachments. Inline image attachments are already handled by
appending an image tag at the end if the content-id is not found in the
body. A sample conversation to test this behavior is
[here](https://app.chatwoot.com/app/accounts/1/conversations/46732).
- We observed in prod for certain emails active storage blob objects
were getting created with empty file name. The conversations further
causes conversation and filter pages to break. This change will fix the
mentioned issue.

Some email clients automatically set Content-Disposition to inline for
specific content types, such as images. In cases where the email body is
empty, inline attachments may not display correctly due to our previous
implementation. Our assumption was that these attachments are referenced
within text/plain or text/html parts.
Customer-reported issues, especially with Apple Mail, show emails with
attachments marked as inline but without any corresponding text parts.
This leads to missing attachments even though would have processed the
attachment.
This update introduces a check for the presence of a text part. If none
exists, inline attachments are treated as regular attachments and added
to the external attachments array, ensuring that all attachments display
properly.

Message search would frequently timeout. The reason was that the query would join the conversation too, the new query searches the message table directly

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.
Fixes#2520
Configuring an agent email also as a support email inbox leads to conversations getting created in a loop if notifications were also configured to the same email.
For emails forwarded from google groups, Google rewrites the FROM address to the group email and the original email will be available under X-Original-Sender. This PR enables chatwoot to handle this case.

* feat: added support mailbox to handle email channel (#140)
Added a new mailbox called 'SupportMailbox' to handle all the
incoming emails other than reply emails.
An email channel will have a support email and forward email
associated with it. So we filter for the right email inbox based on
the support email of that inbox and route this to this mailbox.
This mailbox finds the account, inbox, contact (create a new one
if it does not exist) and creates a conversation and adds the
email content as the first message in the conversation.
Other minor things handled in this commit:
* renamed the procs for routing emails in application mailbox
* renamed ConversationMailbox to ReplyMailbox
* Added a fallback content in MailPresenter
* Added a record saving (bang) versions of enabling and disabling
features in Featurable module
* added new factory for the email channel
