Hi, I'm getting closer, now with SMTP permitted to whole of Internet to connect to my SMTP/postfix server & for my postfix server to connect out to public Internet on tcp 25 as well.
I send emails from permitted SMTP servers with "Receipt acknowledgemt" & the ack returned said it was delivered but somehow there's no mail in the mailbox & using the site below to test, it gave Rejected : http://legacy.zoneedit.com/whois.html OK, connected to gate1.mds.com.sg... < 220 gate1.mds.com.sg ESMTP > HELO edit.dnsvr.com < 250 gate1.mds.com.sg > MAIL FROM:<sender...@mds.com.sg> < 250 sender <sender...@mds.com.sg> ok > RCPT TO:<recipient...@myportaltech.com> < 550 #5.1.0 Address rejected. =================== latest maillog ====================== Feb 21 16:36:34 hostname postfix/smtpd[1372]: input attribute value: 0 Feb 21 16:36:34 hostname postfix/smtpd[1372]: private/rewrite socket: wanted attribute: transport Feb 21 16:36:34 hostname postfix/smtpd[1372]: input attribute name: transport Feb 21 16:36:34 hostname postfix/smtpd[1372]: input attribute value: relay Feb 21 16:36:34 hostname postfix/smtpd[1372]: private/rewrite socket: wanted attribute: nexthop Feb 21 16:36:34 hostname postfix/smtpd[1372]: input attribute name: nexthop Feb 21 16:36:34 hostname postfix/smtpd[1372]: input attribute value: myportaltech.com Feb 21 16:36:34 hostname postfix/smtpd[1372]: private/rewrite socket: wanted attribute: recipient Feb 21 16:36:34 hostname postfix/smtpd[1372]: input attribute name: recipient Feb 21 16:36:34 hostname postfix/smtpd[1372]: input attribute value: r...@myportaltech.com Feb 21 16:36:34 hostname postfix/smtpd[1372]: private/rewrite socket: wanted attribute: flags Feb 21 16:36:34 hostname postfix/smtpd[1372]: input attribute name: flags Feb 21 16:36:34 hostname postfix/smtpd[1372]: input attribute value: 2048 Feb 21 16:36:34 hostname postfix/smtpd[1372]: private/rewrite socket: wanted attribute: (list terminator) Feb 21 16:36:34 hostname postfix/smtpd[1372]: input attribute name: (end) Feb 21 16:36:34 hostname postfix/smtpd[1372]: resolve_clnt: `' -> `r...@myportaltech.com' -> transp=`relay' host=`myportaltech.com' rcpt=`r...@myportaltech.com' flags= class=relay Feb 21 16:36:34 hostname postfix/smtpd[1372]: ctable_locate: install entry key r...@myportaltech.com Feb 21 16:36:34 hostname postfix/smtpd[1372]: extract_addr: in: <r...@myportaltech.com>, result: r...@myportaltech.com Feb 21 16:36:34 hostname postfix/smtpd[1372]: >>> START Recipient address RESTRICTIONS <<< Feb 21 16:36:34 hostname postfix/smtpd[1372]: generic_checks: name=reject_invalid_hostname Feb 21 16:36:34 hostname postfix/smtpd[1372]: reject_invalid_hostname: gate1.mds.com.sg Feb 21 16:36:34 hostname postfix/smtpd[1372]: generic_checks: name=reject_invalid_hostname status=0 Feb 21 16:36:34 hostname postfix/smtpd[1372]: generic_checks: name=reject_unauth_pipelining Feb 21 16:36:34 hostname postfix/smtpd[1372]: reject_unauth_pipelining: RCPT Feb 21 16:36:34 hostname postfix/smtpd[1372]: generic_checks: name=reject_unauth_pipelining status=0 Feb 21 16:36:34 hostname postfix/smtpd[1372]: generic_checks: name=permit_mynetworks Feb 21 16:36:34 hostname postfix/smtpd[1372]: permit_mynetworks: gate1.mds.com.sg 203.126.130.157 Feb 21 16:36:34 hostname postfix/smtpd[1372]: match_hostname: gate1.mds.com.sg ~?
