Yeah, I basically check for one @ sign and some very basic sanity checking on the right side.

/^[^@]+@[^@]+\.[^@.]+$/

As I just noticed, @ is valid in the local part of an email, too, it just has to be properly quoted (using \ or " "). You can send me email at

    "a# b.@c"@[IPv6:2001:4dd0:fc8c::1]
    a#\ b.\@c@[IPv6:2001:4dd0:fc8c::1]

now :-)
