Sorry CJ. I really need to let other people help out here when they can.
I'll try not to be so quick. ;)
You make a good point. Things do change. If the recipient server had
installed spamdyke, this would result in pretty much the same rejection
(message wording might be slightly different).
Thanks CJ. Please keep it up!

Actually I agree, but wonder too were you able to send e mails before to
this address without issue? If so, it sounds like the recipient mail
server is changing their e mail policy.

The firewall has nothing to do with your problem. The change is
coincidental.
Your problem is that the rDNS for your IP address does not resolve:
$ host altcladding.com.ph
altcladding.com.ph has address 122.3.237.67
altcladding.com.ph mail is handled by 10 mail.altcladding.com.ph.
$ host mail.altcladding.com.ph
mail.altcladding.com.ph has address 122.3.237.72
$ host 122.3.237.72
72.237.3.122.in-addr.arpa domain name pointer 122.3.237.72.pldt.net.
$ host 122.3.237.72.pldt.net
Host 122.3.237.72.pldt.net not found: 3(NXDOMAIN)
$
It would be best if the rDNS record pointed to mail.altcladding.com.ph
instead of 122.3.237.72.pldt.net, but if there were simply a (type A)
DNS record for 122.3.237.72.pldt.net, that would suffice.
This is something that your ISP (who provides the IP address to you)
needs to fix for you. You need to contact them to get it changed. They
should have a procedure in place, either a web app or manually, to
change the rDNS record for your IP address(es). You'll need to provide
them with the name you would like to use (mail.altcladding.com.ph). Of
course, you also need to be sure that mail.altcladding.com.ph resolves
to that address, which it does.
