Whenever I enter any server on Minecraft, if I press T and write later on I can't send that message to the chat. I've already tried removing /bin folder and letting the game download it again, but that didn't work.

If the server is running mods, it's possible that new players aren't given the ability to publicly chat until they've "proven" themselves. (Though it does seem odd.) Check the server's web page, if it has one, or try contacting the server admins out-of-game to check whether this is the case.
If you're allowed, you can also post the server's address and port here and I (and probably others) would be happy to report whether we have the same problem on it. :-)
