Hi Louis Tao, For pattern check I can use regular expression. But what I meant is SMTP check. To simulate this, you can go to http://www.network-tools.com, choose "Email Verification" and have an email address as input.
You will have a result comprising of SMTP commands to check the validity of the email. Result example are like below. Question is, with Java Mail API can we have the same process without sending the message itself, but check the validity of the email address first ? Thanks, Feris *Validation results* canonical address: <java.phiintegrat...@gmail.com> *MX records* preferenceexchangeIP address (if included)*5**gmail-smtp-in.l.google.com** [0.0.0.0]**10**alt1.gmail-smtp-in.l.google.com**[0.0.0.0]**20** alt2.gmail-smtp-in.l.google.com**[0.0.0.0]**30** alt3.gmail-smtp-in.l.google.com**[0.0.0.0]**40** alt4.gmail-smtp-in.l.google.com**[0.0.0.0]**SMTP session* [Resolving gmail-smtp-in.l.google.com...] [Contacting gmail-smtp-in.l.google.com [74.125.157.27]...] [Connected] 220 mx.google.com ESMTP f29si23779669anh.116 EHLO Network-Tools.com 250-mx.google.com at your service, [67.222.132.194] 250-SIZE 35651584 250-8BITMIME 250 ENHANCEDSTATUSCODES VRFY java.phiintegration 252 2.1.5 Send some mail, I'll try my best f29si23779669anh.116 RSET 250 2.1.5 Flushed f29si23779669anh.116 EXPN java.phiintegration 502 5.5.1 Unimplemented command. f29si23779669anh.116 RSET 250 2.1.5 Flushed f29si23779669anh.116 MAIL FROM:<ad...@network-tools.com> 250 2.1.0 OK f29si23779669anh.116 RCPT TO:<java.phiintegrat...@gmail.com> 250 2.1.5 OK f29si23779669anh.116 RSET 250 2.1.5 Flushed f29si23779669anh.116 QUIT -- To post to this group, send email to javaprogrammingwithpassion@googlegroups.com To unsubscribe from this group, send email to javaprogrammingwithpassion+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/javaprogrammingwithpassion?hl=en
