See how the original MAIL FROM data is fully lost while the rest now needs
to be processed via RegEx to the detriment of the user?
RFC-2822 clearly distinguishes the nature of both sets of data, reason
while nearly every single SMTP server will provide you with the option of
logging the details provided during the SMTP exchange (envelope), while mail
parsers will usually look into the Headers of the message (EmailExtractHeaders
does that)
>
> MAIL FROM:<>
>
> As discussed in section 2.4.1, a relay SMTP has no need to inspect or
> act upon the headers or body of the message data and MUST NOT do so
> except to add its own "Received:" header (section 4.4) and,
> optionally, to attempt to detect looping in the mail system (see
> section 6.2).
