The Zabbix server is working.
But sometimes (every few days, increasingly) the alarm e-mails cannot be sent with the following message: 'cannot connect to SMTP server "own.mail.server": cannot resolve [own.mail.server]'.
This issue only can be solved by restarting the 'zabbix_server' service.
The mail server is also working, we can send e-mails (checked with swaks).
I've tried to put the mail server's IP address into the hosts file (although, the DNS service is running and working correctly), but the situation is the same.
I couldn't find any relevant details in log file.
I'd like to ask you to examine this trouble or give advices how can/should I solve this.
Thanks in advance.
