Hello,
I have problems to send mail to comast.net, a provider located in th US.
We are located in Japan though.
The error message is
"450_(TEMPFAIL)_comcast.net_requires_valid_sender_domain".
My understanding is that in the example below the sender domain should
be "choicenet.ne.jp". Is it correct to conclude that comcast.net has
problems to validate this domain?
We have Japanese domains ( .jp, co.jp) and .com domains. I checked them
with DNSREPORT and they seem to be ok.
Did the same with DNS Crawler and it seems that DNS Crawler works fine
for our Japanese domains (e.g. enaki.jp) but NOT with .com domains
(e.g. japanpsychiatrist.com).
I also checked the SPAMHAUS.ORG blacklists but our IPs (203.141.151.199,
203.141.151.81) are not listed.
Can anybody shed some light into this issue?
All help is appreciated.
Kind Regards,
Bernd
