[parcival]

Hi all and happy new year.
i get this error message (mail logfile) with net.tcp.service[smtp]

Jan  3 13:12:39 ns1 sm-mta[3107]: p03CCdkb003107: localhost [127.0.0.1] did not issue MAIL/EXPN/VRFY/ETRN during connection to Daemon0
Jan  3 13:13:41 ns1 sm-mta[3134]: p03CDfhV003134: localhost [127.0.0.1] did not issue MAIL/EXPN/VRFY/ETRN during connection to Daemon0
Jan  3 13:14:41 ns1 sm-mta[3161]: p03CEfDG003161: localhost [127.0.0.1] did not issue MAIL/EXPN/VRFY/ETRN during connection to Daemon0
Jan  3 13:15:40 ns1 sm-mta[3345]: p03CFext003345: localhost [127.0.0.1] did not issue MAIL/EXPN/VRFY/ETRN during connection to Daemon0

zabbix_get -s192.168.1.12 -knet.tcp.service[smtp,{HOSTNAME}] give the same error.
What must i do in sendmail, that he accepts smtp connections of the agent (127.0.0.1 or Hostname)?

thx

I have discussed these problems in the FreeBSD forum.
There are they of the opinion, that this Key "net.tcp.service[smtp]" should be optimised.

There is nothing wrong with your Sendmail. Note that Sendmail is complaining about the connecting party not setting up a proper SMTP session or issuing a proper SMTP command (like the ones in the error message). This is correct, because all Zabbix does is send a tcp packet to elicit a response from port 25 and probably harvest the result code and the hostname in the process, because that's all you get from a connection.

Those messages can be useful to see when a spammer has given up. Seems like it would be better to fix the Zabbix stuff to actually do something minor on connect instead of just hanging up.

i do not think i was ready for you to put words in quotation marks. i'll think about what you really want when you put your search in quotes and try to return something that makes sense.

zabbix_get -s192.168.1.12 -knet.tcp.service[smtp,{HOSTNAME}] give the same error.

What a fuzz about nothing... It's not an error, it's just a warning.
You can also see it as a way to recognize the zabbix agent.
