i am suspecting that this may matter because for some reason, the email header at yahoo shows:
Received: from 126.96.36.199 (EHLO mail.quatiseasia.com) (188.8.131.52) by mta126.mail.re2.yahoo.com with SMTP; Wed, 01 Mar 2006 19:24:04 -0800
and the ip address of mail.quatiseasia.com is 184.108.40.206 - doesn't match 220.127.116.11 - and thus went straight into spam filter...
i've added a PTR record for 18.104.22.168 - maybe i need to wait for TTL of 24 hours before it will take effect and hopefully yahoo/hotmail will deliver my mails to inbox instead of junk mail folder!
lets hope for the best...
