Error when message hasn't "To:" header

[lmorillas]

The "to:" header isn't mandatory in imap and some clients doesn't include it or maybe the user sends a message with a bcc header. If the message has no "to" header, helpdesk raises an ERROR: ERROR -- : MailHandler: an unexpected error occurred when receiving email: undefined methodformatted' for nil:NilClass It creates an issue but incomplete: without the owner-email header i.e.

You can test it with a fixture without the to header:
