is it possible to validate emails on a certain field on filemaker 5.5?

ex: when user enters email address

1. enter on a certain field: hello@example,com

user enters invalid char "," would it be able to correct or prompt the error?

Yes, to an extent.

You could validate the entry to ensure that it contains no forbidden characters (spaces, commas etc) and satisfies other minimum requirements (contains one "@" character, etc).

It is not possible to actually check that the e-mail address is "real" without somehow checking with the mail server. This, if it is possible with FMP, would require the use of a plug-in.

.. or the use of web services and XML

.. or a simple perl script using the Mail::Checkemail module

I do this using a perl cgi and XML/XSL import.

However, most mailservers nowadays do not allow for those checks anymore because of spammer's abuse.
