 New Comment:

We don't document that limit, so the idea that e-mail addresses >254 characters may be
validated seems to be expected behaviour to me.

Closing not a bug.

string(258)
""xxxx"."xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxx.com"
string(260)
""xxxx"."xx"."xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxx.com"

etc etc etc also all validate as valid emails (take one local character away for every dot separated
quoted group you add

Description:
------------
following along with http://squiloople.com/2009/12/20/email-address-validation/
(php uses this syntax for the filter) 

"limiting the entire length to 254 characters"
254 is brought up several times yet the following code validates and is 256 characters 

caused trouble for mysql setting a column to 254 expecting that to be the max size

Test script:
---------------
var_dump(filter_var('"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.xxxxxxxxxxxxxxx.com',FILTER_VALIDATE_EMAIL));
