There is no way to do it correctly without sending an email and see if 
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 = adress.split('@')
        domain, topDomain = 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 
harder.

you could then call it like:

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