Hey @frost
Currently we only support email to ticket creation for registered contacts.
Where an email isn't recognised as belonging to a contact, we then check if the domain matches a client. If it does, we automatically create a contact and raise the ticket under them.
If both of these checks fail, the email is left in the inbox but flagged. You quite literally need to login to the mailbox setup for ITFlow and manually check that flagged email.
It was built this way to avoid spammy emails generating tickets. In future we might add some sort of "inbox" in ITFlow where you can choose to ignore / create tickets from these sorts of emails.
Hope this helps!
