more reliable search results

[gene-miller]

When using the mailhog search via the API and the UI, the search is performed on the 'Source' data.

We have found this produces unreliable results when using Content-Transfer-Encoding: quoted-printable

For example:

Plain text:
"
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut tortor
tellus, venenatis eu molestie a, gravida a quam. Maecenas laoreet
ullamcorper enim. Duis et massa sed lorem tincidunt congue.
"

Source:
"
Content-Type: text/plain; charset=utf-8

Content-Transfer-Encoding: quoted-printable

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut tortor
tellus=
, venenatis eu molestie a, gravida a quam. Maecenas laoreet
ullamcorper e=
nim. Duis et massa sed lorem tincidunt congue.

Content-Type: text/html; charset=utf-8
Content-Transfer-Encoding: quoted-printable
"

A search for the string "Ut tortor tellus, venenatis eu molestie" will return no results due to the "=" characters inserted by quoted-printable.

It would be great to have the option to search the "Plain text" especially via the API.
