There is no issue sending to the smtp server, because other scripts send
successfully mails to this server. Only ossec does not send any mails,
as far as I can see. It's still a puzzle.
Thanks!

We have 3 servers running OSSEC (standalone). One server runs CentOS 6,
the two others opensuse 15.1. The configuration of OSSEC is almost
identical on all three servers (as close as possible).
The CentOS Server sends a lot of emails, one of the opensuse servers few
and the third server (opensuse) no emails. But in the log I see issues
they should lead to sending an email.
The server is able to send emails to the configured server. I see no
messages about errors sending emails. In /var/ossec/etc there is a copy
of resolv.conf. OSSEC version is 3.3.0.
What can I do?
Are they sending to the same smtp server?
If you have access to the mail server logs, you could check there.
Otherwise, you could use tcpdump to see if there are any issues.
