Zabbix gmail notification with postfix

[Thyagaraj]

How to perfectly configure zabbix gmail notification with postfix(relay to gmail)
Actually this setup is working on my local machine but when I try to implement this on my real servers, email notification is failed and I could see the following error in audit

Cannot connect to SMTP server [localhost] [gethost() failed for address 'localhost' [Success]]

my /var/log/mail.log message

Aug 26 00:14:31 station1 postfix/smtpd[9385]: connect from localhost.localdomain[127.0.0.1]
Aug 26 00:14:31 station1 postfix/smtpd[9385]: disconnect from localhost.localdomain[127.0.0.1]
Aug 26 00:15:31 station1 postfix/smtpd[9385]: connect from localhost.localdomain[127.0.0.1]
Aug 26 00:15:31 station1 postfix/smtpd[9385]: disconnect from localhost.localdomain[127.0.0.1]


Thanks all!

Smtp server is runnig correctly?

try

telnet localhost 25
helo yourdomain
mail from: <>
rcpt to: <[email protected]>
data
Enter message here
.
exit

When I use telnet command on ubuntu, I'm getting following error:

-bash: /usr/bin/telnet: No such file or directory

Regarding this I posted in ubuntu forum and i'm asked to remove telnetd and install only telnet client(telnet). I did as it is said but no change with same problem as above.

This is a link that i used last week, we use postfix to relay mails to google on our ec2 servers.

Now my smtp is working fine(checked telnet localhost 25) and I could send mail from command line like this 'mail -s "hello" [email protected]. But i'm getting the same above posted error in the Audit>Actions.
This is my media settings and this is the same settings which is working on my local machine

Media
Description:
Type E-mail
SMTP server: localhost
SMTP helo: localhost
SMTP email: root@localhost

Zabbix E-mail notification error(audit->actions):

Cannot connect to SMTP server [localhost] [gethost() failed for address 'localhost' [Success]]

You probably need to customise the helo name to a domain that is accepted by postfix. The actual hostname of the machine usually works. Besides that, it's better to change the SMTP email address to some address in your domain, like [email protected]

Is there any way so that I force zabbix to send email immediately?.

Here are my settings.
