Re: email verification2011-08-07T11:53:52Z in response to fachhochWith 'email verification' do you mean checking if the provided address actually exists, or only checking if the address is well formed ? In this last case, you can try regular expressions.. on web, you'll find a lot of examples you can use.
To check if an email address really exists, the only way I can think to it's to search for an SMTP Java api which may let you to work with SMTP protocol at a very low level.. as far as I know, if you TELNET to an SMTP server and try to issue a SEND TO:<unexistent alias>, mail server may reply with something like 'Unknow alias'. But a mail server may even discard your request silently, if a target mail address doesn't exist, to avoid SPAM attacks (at least, I've seen mail servers behaving this way); I think the best way is to send a mail to provided address, including a 'confirmation URL' that user must click on to confirm validity of email provided.
