Why isn't the result of cron being sent to EXIM?

Question

Exim

The problem of mail support was solved using pdd.yandex.ru.
But to send mail from the server, I had to install exim4 and configure it in smarthost mode

dc_eximconfig_configtype='smarthost'
dc_other_hostnames='domain.ru'
dc_local_interfaces='127.0.0.1 ; 192.168.122.10'
dc_readhost=''
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost='smtp.yandex.ru::587'
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname='false'
dc_mailname_in_oh='true'
dc_localdelivery='mail_spool'

The passwd.client file has a link to the mailbox.
Everything started up and went.
When sending a text message from the shell, the message normally works out and reaches the sender, leaving in the log
echo "foo" | mail -s test1 report

Perfectly fulfills and delivers logwatch mail log.
But when specified in the cron to send outputs to soap [email protected] for some reason I get in the log

2014-08-25 19:14:03 1XLvy7-0000Pg-5u Frozen (delivery error message)

Changing the EMAIL address in crontab did not lead to a different result.
I will also be glad to help in obtaining a more detailed log than the one indicated above, unfortunately I myself did not find how to get it, I want to see everything that 2 servers are talking about at that moment.

Answer 1

Now I can sleep peacefully, the problem is solved

dc_eximconfig_configtype='internet'
dc_readhost='domain.ru'

Having brought these variables to the specified form, my problems disappeared - letters come from the console and when working out the crown.
Why so - I can’t say, because unfortunately I didn’t manage to achieve a complete log of communication between my host and Yandex, so this part of the problem remains open for your suggestions.
