[Zope] Valid email address...

[Michael Fox]

Cheers Max, that's exactly what I needed. Simply to check if the string
contains those values..

something@something.something

The fact that is is or isn't a real email address is not an issue for me
ATM.

Thanks,
Michael.

There is no way to do it correctly without sending an email and see if=20
you get an reply, so don't sweat to much over it.

I usually just do something like:

def isValidMail(adress):
    return '@' in adress and '.' in adress

or if you are a bit more paranoid:

def isValidMail(adress):
    if '@' in adress and '.' in adress:
        id, url =3D adress.split('@')
        domain, topDomain =3D url.split('.')
        return len(id)>0 and len(domain)>0 and len(topDomain)>0
    return 0

In practice you cannot really do much better even though you tried much=20
harder.

you could then call it like:

<dtml-if "isValidMail(adress)">
do stuff
</dtml-if>
