zabbix stops sending e-mails

[ShivaS]

Hi, from time to time i am experiencing problem where zabbix stops sending e-mails. I just notice in actions that mail has status "not sent"
and only restarting server resolves the problem.
I am now implementing some false trigger to check some file and send me mail every 10 minutes. Once my script would notice status of that specific trigger's action in mysql as "not sent" zabbix server is restarted.
But may be there is something else i may do without going too deep into additional scripting?

Hi,
i use version 1.1beta2 and the zabbix server sends more than 20 mails per day. And everything is working fine. Maybe your mailserver is the problem. Could you check this?

i have several dozens servers with at least 10 monitors for each, kinda complicated system.
zabbix executes around 100 mails per day for different monitor/alert issues.
mail server ain't problem, i gave zabbix my ISP mail server, though local postfix also works good.
only after zabbix restart it sends again until would stuck...usually once a day or two...

thanks
