This code is close, but does not allow addresses ending in .museum or .travel.
That's because the code limits the TLD to have between 2 and 4 characters. I would suggest relaxing the rules a little and not impose an upper limit (i.e. only a minimum of 2 characters). Thus line 6 ought to be:
if (!preg_match('/^[_A-z0-9-]+((\.|\+)[_A-z0-9-]+)*@[A-z0-9-]+(\.[A-z0-9-]+)*(\.[A-z]{2,})$/',$email)) {
