Tim Allison commented on TIKA-3489:
-----------------------------------

I added mime detection for robots.txt in {{main}} with mime {{text/x-robots}}.  
We can change this before the next release if there are objections.

> Robots.txt files frequently identified as message/rfc822
> --------------------------------------------------------

> The Tika MIME detector recognizes a robots.txt file as "message/rfc822" if 
> the file starts with a "User-Agent" rule and contains also a second rule not 
> too far away from the beginning, e.g.:
> {noformat}
> User-Agent: goodbot
> Disallow:
> User-Agent: badbot
> Disallow: /
> {noformat}
> The change 
> [7769a2b|https://github.com/apache/tika/commit/7769a2b4fba2b4af7127eba0c7694f663fd97a13]
>  requires that two different clauses are matched. However, the two 
> occurrences of "User-Agent:" (initial and after a new line) are treated as 
> different instead of equivalent matches.
