Thanks.

If you're looking to verify if it's in the traditional user@dom.ain format, that's easy enough... But if you want to know if it's an actual working address, you'll have to actually send something to it.

To verify the format, I would do an Instr search to find the @, iterate through the part before it to check for alphanumeric only, then split the other part by periods (.) and check for alphanumerics and dashes surrounded by alphanumerics.

Hmm, looking at Sethi's comment, it's nice to be proven wrong.

YOu have to correct the sysntaxes:

function checkemail(strEmail) as boolean
    If Len(strEMail) < 5 Exit function                              ' Minimum length check
    If InStr(strMail, "@", 1) = 1 Exit function                  ' Must contain @ symbol
    If InStr(strMail, ".", 1) = 1 Exit function                    ' Must contain . symbol

    checkemail = true
end function
