Combine multiple alerts into a single email?

[sashk]

Hi,

I've got multiple checks per host and when host is down, or host has multiple 
alerts, I end up receiving multiple emails per host. Is there a way to combine 
them into a single alert?

Example config:

check host smtp.domain.com with address smtp.domain.com
 if failed ping then alert
 if failed port 25 protocol smtps certificate valid > 30 days then alert
 if failed port 587 protocol smtps certificate valid > 30 days then alert
 ...


Thanks!
