email

Just when I decided not to blog too much, I stumbled upon this nice pictureI happened to notice a email address in our system that was 33 characters + @ + domain name and got kind of curious about how long they can be.
Aparently they can be longer than what anyone could ever want, which doesn't necesarily mean that addresses close to the limit will work everywhere.
If I understand things right the username part can be up to 64 characters and the domain can be 255 characters; the total length of a email address can not however be longer than 254 characters.

(Here is where I found the picture and the information on how long the address can be)
