However this is not required in order to check for an email adress. The following SMTP transaction tests two gmail addresses (mine and a bogus one) without sending any mail : $ telnet gmail-smtp-in.l.google.com 25 220 mx.google.com ESMTP 5si857404ewy.28 EHLO ibook-g4.elimerl.fr 250-mx.google.com at your service, [89.85.146.36] 250-SIZE 35651584 250-8BITMIME 250-ENHANCEDSTATUSCODES 250 PIPELINING MAIL FROM: <postmaster@ibook-g4.elimerl.fr> 250 2.1.0 OK 5si857404ewy.28 RCPT TO: <elimerl@gmail.com> 250 2.1.5 OK 5si857404ewy.28 RSET 250 2.1.5 Flushed 5si857404ewy.28 MAIL FROM: <postmaster@ibook-g4.elimerl.fr> 250 2.1.0 OK 5si857404ewy.28 RCPT TO: <thisaddressdoesnotexist@gmail.com> 550-5.1.1 The email account that you tried to reach does not exist. Please try 550-5.1.1 double-checking the recipient's email address for typos or 550-5.1.1 unnecessary spaces.

For example, Yahoo! will always answer "OK" to the RCPT TO command, and report an error only after an email has actually been sent. However, this is a postfix feature, so I guess it works quite well.
