I'd personally recommend leaving phone numbers alone :-) Too many folk
have different ways of writing phone numbers, or need to add something
like "and then push #3 and ask for Tracy" to the end.

You can check an e-mail has the correct structure - but you can't
check that the e-mail is "correct" (without actually sending the e-
mail and having the user confirm.)

Define "reliable"? Is the issue it not being filled in at all? Being
filled in with bogus info? Something else?

Whether it's possible or not will depend to some extent on the
motivation of the user. I'm highly motivated to put my phone number on
some forms (e.g. when expensive hardware is being delivered and they
need to check somebody is in). In others I will go out of my way to
give a fake number (e.g. when I'm forced to register one when
downloading a demo and want to avoid the annoying sales calls.) The
data bods should find the idea of incorrect data more frightening than
absent information - so that's a useful axe to wield.

Again - depends on the motivation. I'd be happy to be reminded that
I've forgotten my postcode on a form for where my parcel should be
delivered. I'd find it annoying when the address is irrelevant to the
action I'm trying to take.

The usual pointer to Luke Wroblewski's "Web Form Design" book :-)
