Use one of many SMTP endpoints

Hi,

I’m building out some notifications with Grafana.

I’ve been given a number of SMTP servers that can deliver mail on Grafana’s behalf, is it possible that I list out every SMTP server in the grafana.ini file or am i restricted to only 1 entry for the ‘host’ value?;

Currently trying to to this;

[smtp]
enabled = true
host = “server1:25”, “server2:25”, “server3:25”
from_address = grafana-alerts@grafana.local
from_name = Grafana

t=2020-08-03T13:02:17+0100 lvl=eror msg=“failed to send notification” logger=alerting.notifier uid= error=“address “server1:25”, “server2:25”: too many colons in address”

Thanks!
