1024+ byte body and youtu.be link

Since 2021-01-05 the amount of mails hitting SHORT_SHORTNER has increased with
more than 2000%...

Some testing shows me that
1: It hits mails with body larger than 512 bytes
2: youtu.be is considered an url shortener

As far as I can tell the __PDS_MSG_512 meta rule that SHORT_SHORTNER is based
on should only trigger for bodies smaller than 512B, should it not?

I can't say I really agree with the classification of youtu.be as a
urlshortener either, but that's not the main problem here, the body size is. As
far as I know youtu.be can only be used for links to youtube videos and is not
a all purpose shortener.

Including example mail trigger the rule. It has 1024 bytes of lorem ipsum in
body, and a youtu.be link
