Mailing List Archive
Finding a message inside the official archive of a mailing list is
hard because the mailing list's site does not contain a search engine.
Even with a search engine it is not easy. Today I looked for one of my

In that site, you can find a search box, and can search according to
list name, subject, authors or bodies.
For bodies, you have to select a list first.
Now you can find your messages more easily.
