Can't read notification email

[gao]

I just installed Zabbix 2.4 on my Centos6 server. Since I already have a setup on my server using sSMTP to send email vis Gmail, so I made script followed the instruction here:

http://www.tecmint.com/configure-zabbix-to-send-email-alerts-to-gmail/

Now the alert email send to the recipient. But the email received has a blank body with an attachment. And in my Thunderbird I cant open up the attachment. Viewing the source I see the attachment is not plain text.

So I might missing something here. Please help. Thanks.

Finally I found out the solution.

This is because mailx on CentOS6 having this issue:

https://access.redhat.com/solutions/1136493

Mailx expects input text to be in Unix format, with lines separated by newline (^J, \n) characters only.
Non-Unix text files that use carriage return (^M, \r) characters in addition will be treated as binary data; to send such files as text, strip these characters e. g. by

tr -d ’\015’ <input | mailx . . .

Now the question is why zabbix's output using non-unix format???

the solution is to install bsd-mailx instead and then force it's use:

To install:
sudo yum install bsd-mailx

To make it use bsd-mailx:
sudo alternatives --set mail /usr/bin/bsd-mailx

To check what it's using:
sudo alternatives --display mail

You may also have to alter the script you are using in zabbix to send the mail.
