Hi Remo,
nothing really important, but in current NeDi 1.0.8 installations, all with moni service active, when there is more than one alert in one message, the "pluralizer" make a strange thing in the message object field.
Below an example:
"2 2 Monitoring Alertss"
i.e. it doubles the alerts number text (is really 2), and adds "s" twice at the end.
I had a look at relevant code, and seems good, but I'm not skilled enough to be a reliable debugger.
I repeat, is only a cosmetic issue.

P.S. I'm almost sure it doesn't depend on our SMTP servers, there are a lot (myriad) of other messages sent from other servers and services, without any similar issue.
