function IsValidEmail(email)
dim names, name, i, c
IsValidEmail = true
names = Split(email, "@") 是否含有郵箱的必需條件@字符
if UBound(names) <> 1 then

IsValidEmail = false
exit function

for i = 1 to Len(name)
c = Mid(name, i, 1)
if InStr("abcdefghijklmnopqrstuvwxyzaBCDEFGHIJKLMNOPQRSTUVWXYZ_-.", c) <= 0 and not IsNumeric(c) then ‘限定某些特定字符
IsValidEmail = false
exit function
