[1.1b7] False triggers on SMTP servers

[Wido]

Hello,

I have been running Zabbix 1.1Beta7 right now for a week now and i get a lot of false results with my SMTP servers.

Currently i am monitoring 10 hosts with Zabbix and i get a lot of false reports with SMTP servers.

6 servers are running Exim, 1 is running Postfix en 1 is running Qmail.

The other 2 don't run a SMTP server.

When i get an alert i check my SMTP server and it is running without any troubles.

I can't be the netwerk, since all the other checks like HTTP, FTP, POP3 and IMAP are running fine.

Maybe it is de timeout value that is to low, can i increase this for ONLY the SMTP check? Or is it something else?

Thank you,

Wido

Kind off the same problem here.
I got several servers running zabbix_agentd sending http,ftp and smtp info using check_service[smtp] . They are all working fine except for one. This one works for system[procload] and memory[free] but refuses to work with check_service[smtp]. I get a response about once an hour, so sometimes it does work. I know if I telnet to port 25 on this server it responses in about 10 seconds (is this to slow for the agent). I have set the timeout to 25 sec on the agentd.conf.

server: zabbix1.1beta11 (pages still say beta10??)
agentd: beta2 on freebsd6.1
(BTW zabbix_agentd -p seems to hang after
check_service[*] [ssh,127.0.0.1,22] [1.000000] )
