[bug] fix extraction of uuid from message headers
Before this commit, the mail receiver system used to compare the domain of the delivery addresses found in the "Delivered-To" header to find out the final delivery address. If we assume that the mail server delivery to the spool mail directory was correct, then we have two facts: (1) the topmost "Delivered-To" header is the one that indicates the correct final delivery address; and (2) we should expect the address to be <uuid>@<domain> because of the earlier alias resolve query made by the mail server. Another problem is that the domain comparison would compare whatever is in the "Delivered-To" header with whatever the python's socket module would return, which depends on the values on /etc/hosts and the order of the values in that file. This was causing problems whenever the platform made changes in /etc/hosts. So this commit eliminates the domain check and gets the uuid from the first "Delivered-To" header found in the message. Related: #6858.
