Incoming Emails

[rabii]

probably the lead's email was bbc into the email. still it shouldn't happen hence the email coming to is not in the system. try to check records in db

Please explain how the incoming email is matched with the lead? We have a case when a letter came from an address that is not in the system and was attached to a lead that has different email. Is there a way to check that everything is correct or is it a bug?
