There is this cute suggestion in the Wrox PHP book:
/^.+@.+\\..+$/
Looks like a puzzle, but it works (almost) always.

Regarding the problem you are actually asking about:

Please be aware that I use PCRE not POSIX, but IIRC the last phrase says:
([A-Za-z]{2,3})+$
any upper or lower case letter,
repeated twice or three times,
and that appearing zero or more times, !!!???
appearing at the end of the string.
Remove the + immediately before the terminating $.
