I install a JBossMailServer1.0M4 by default.(see http://wiki.jboss.org/wiki/Wiki.jsp?page=HowToInstallJBossMailServer1.0M4) Certainly, I set a DNS for sending Email out. When I send emails from test@localhost to wrwttkl22(a)163.com, wrwttkl22(a)sohu.com or wrwttkl22(a)126.com, I can receive all with them. But I send an email from test@localhost to wrwttkl22(a)hotmail.com , I can not receive the email with wrwttkl22(a)hotmail.com. why? hlep! thank you!
