Hello!
One of the mail users have problems sending mails to other domains. Looking
at the logs, they display:
Aug 17 09:49:55 mail postfix/smtpd[24050]: NOQUEUE: reject: RCPT from *****.
technowave.ne.jp[210.150.98.251]: 554 5.7.1 <makoto-****...@asmo.co.jp>:
Relay access denied; from=<noriyuki-***...@yutaka-japan.com>
to=<makoto-****...@asmo.co.jp> proto=SMTP helo=<Y4>
(real emails are hidden)
Other users from the same domain (yutaka-japan.com) are not having problems
with their accounts.
Questions:
1) Why "helo" does not returns a domain name?
- is that correct / normal?
- "Y4" is a proxy server?
2) Does this user has "yutaka-japan.com" as mail server in his/her mail
client config?
- Is there any way to know that?
The normal way which I solve this kind of problem is adding that IP
(210.150.98.251) to mynetworks setting.
But I feel that is not the best way to do it. I would like to know why this
is happening... I have no direct access to user's mail client settings
so I have to assume his/her settings are correct.
Thank you.
A.Lepe
