zext_msmtp stops working

[lokoluka]

Hi All, first of all, sorry for my english. It's not my mother language. Said that I start.

I use zext_msmtp.sh script to send alerts but some days ago it just stopped working.

• I didn't find anything useful in /var/log/zabbix-server/zabbix_server.log.
• I turn the debug option on inside the script and nothing at the begining.
• I run the script manually (/etc/zabbix/alerts.d/zext_msmtp.sh [email protected] "test subject" "test body") and It worked.
• I check logs again and I see everything is ok.
• I add logfile option in /etc/msmtprc (/var/log/zabbix_mail.log)
• I run the script again and everything is ok
• I generate an alert and voila! fields in recipient, subject, and body are empty
• I gererate another alert and check the command used by zabbix (ps ax) and I get these lines:
  
  

  sh -c /etc/zabbix/alert.d/zext_msmtp.sh "[email protected]" "OK: Host: bla bla bla" "more bla blabla"
  /bin/sh /etc/zabbix/alert.d/zext_msmtp.sh [email protected] OK: Host: bla bla bla more bla blabla
  msmtp --account zabbix [email protected]

• I ran the first line as it and I get an error "no recipient argument" (or something like that)
• Then I try two things
  1. I took off -c option (sh /etc/zabbix/alert.d/zext_msmtp.sh "[email protected]" "OK: Host: bla bla bla" "more bla blabla")
  2. I insterted ' (apostrophe) after -c option and at the end (sh -c '/etc/zabbix/alert.d/zext_msmtp.sh "[email protected]" "OK: Host: bla bla bla" "more bla blabla"')
  
  and both worked!!

So I don't know exactly why it stopped working but is like zabbix is sending the wrong command. It's a mystery to me I must confess.

Any help will be appreciated.

Thanks.

I'm not sure if I'll be able to help, but could you provide a bit more information:

1. What Linux distribution are you using?
2. What Zabbix version are you using?
3. Has anything changed or been updated (even anything that you wouldn't expect to be relevant).

Do I understand correctly that you receive the email but it is blank?

Sure, I installed zabbix 2.0.6 on a Linux Ubuntu 12.04.

I had some issues with Miredo so I purged and reinstalled, I changed locales to en_us.utf8, I added one entry to route table, I uninstalled gimp, firefox and thunderbird, and I upgrade some packages.

For your last question, it is not correct. I don't receive any kind of emails if zabbix send them. I only receive them when I send them manually.

I grabbed .bash_history and the apt-get history for that day and I will try to rollback the upgraded packages. If you have another suggestion I'll be pleased to hear it.

I fix it by reinstating on Debian. I just moved the database, config files, scripts, etc to the new server and it started sending emails again.
