Jun 15 11:29:09 smtp sendmail[38987]: u5F8T80T038979: to=<*****@yandex.ru>, delay=00:00:01, xdelay=00:00:01, mailer=esmtp, pri=124135, relay=mx.yandex.ru. [87.250.250.89], dsn=2.0.0, stat=Sent (Ok: queued on mxfront2m.mail.yandex.net as 1465979350-owgLHme2Oc-T9oeKTOB)

This is so vague. I hope support can help with your problem.

Hi,

your problem is with dns. Your host smtp.brain-games.ru is unknown in your zone. So that is why this remote MTA refuses to accept mail from you as it does a lookup of smtp.brain-games.ru. You should be a forward dns and a reverse dns set for your relay server

Regards,
Scalix Support Team

At the moment

brain-games.ru. MX. 10. mail.brain-games.ru. IN. 600.
mail.brain-games.ru. A. 85.143.185.229. IN. 600.

reverse dns:
mail.brain-games.ru [85.143.185.229]

smtp.brain-games.ru - hostname on RHEL.

smtp.brain-games.ru must have a record in DNS?

Hello,

Yes, smtp.brain-games.ru should have dns record. OR if you want to relay through mail.brain-games.ru you should add it as smarthost in sendmail config file.

Thank you

where I have to add smarthost in sendmail config file?

Hello,

Fallow the instruction in http://www.scalix.com/wiki/index.php?title=Configuring_Sendmail_with_smarthost_Ubuntu_Gutsy#Configuring_a_smarthost_for_sendmail

Note: See only the smarthost part

Regards,
Scalix Support Team

edit the file /etc/mail/sendmail.mc

add
define(`SMART_HOST', smtp.brain-games.ru)dnl

result
<smtp.brain-games.ru>: Helo command rejected: Host not found

What could it be?

Hi,

Please try this.

Open your configuration file:


Append or modify macro that read as follows :


Regenerate a new sendmail.cf config file with m4 command:


Restart sendmail service:

Thank you

I added the record dns

my letter has gone.

Try solving DNS issue as suggested. This should work accordingly.
