Problem with SMTP check and zimbra

[guigui]

Hi,

I just upgraded zimbra to 8.7 version, and now SMTP check says it's down... but it's not.

Had a look on wiki, " Creates a TCP connection and expects the first 3 characters of the response to be “220”. Then sends “QUIT\r\n”. Default port 25 is used if not specified. "

Then I tried telnet smtpserver 25, got 220, but a particularity for the 4th character "-".
220-smtpserver

With this "-" as 4th character, net.tcp.service[smtp] check says it's down, with a space as the 4th character, says it's up.

Is this a bug ?

Thanks,
Best regards,

Solved that using this:

Just whitelist zabbix IP, and it's ok ! :-)
