Can you run the following command and send back the output
the command! :
Code: Select all
nslookup -querytype=any deaconsulenze.eu
Server: 10.10.2.102
Address: 10.10.2.102#53
Non-authoritative answer:
deaconsulenze.eu nameserver = ns2003.dizinc.com.
deaconsulenze.eu nameserver = ns2004.dizinc.com.
Authoritative answers can be found from:

That output looks truncated, but similar to a successful name resolution.
If you did successfully resolve the MX record, then I'd next check the network - can you "telnet intra.deaconsulenze.eu 25" from the Nagios server?

Does /var/log/maillog show any other information around the time of the failed Nagios notification?
Try sending a mail manually:
Code: Select all
telnet intra.deaconsulenze.eu 25
HELO <nagios server FQDN> <---- (the output from "uname -n")
MAIL FROM:[email protected]
RCPT TO:[email protected]
DATA
SUBJECT:Test email
[Press Enter twice]
some data
some data
.
The last part is a single "." on a line on it's own, which tells the relay you're done sending data. Post any errors you get from doing this.

Hrm, okay.
What happens if you try:
Code: Select all
su - nagios
/usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: PROBLEM\n\nService: HTTP\nHost: IpCop Milano ESA\nAddress: 192.168.33.1\nState: CRITICAL\n\nDate/Time: Thu Jun 5 14:51:10 CEST 2014\n\nAdditional Info:\n\nHTTP CRITICAL: HTTP/1.0 504 Gateway Time-out - 1937 bytes in 0,183 second response time\n" | /usr/bin/mail -s "** PROBLEM Service Alert: IpCop Milano ESA/HTTP is CRITICAL **" [email protected]

I'm not sure, to be honest! That command is what Nagios runs when the notification is triggered.
One very minor thing - can you "su - nagios", not "su nagios" and run the command again please?

Just to make it a little more clear for you, Stuart would like to see:
Code: Select all
su nagios
/usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: PROBLEM\n\nService: HTTP\nHost: IpCop Milano ESA\nAddress: 192.168.33.1\nState: CRITICAL\n\nDate/Time: Thu Jun 5 14:51:10 CEST 2014\n\nAdditional Info:\n\nHTTP CRITICAL: HTTP/1.0 504 Gateway Time-out - 1937 bytes in 0,183 second response time\n" | /usr/bin/mail -s "** PROBLEM Service Alert: IpCop Milano ESA/HTTP is CRITICAL **" [email protected]
