Avoid email storm

I stop the MTA sometimes when I know this is about to happen.

Subject: [Xymon] Avoid email storm

xymon is behind a firewall and lately firewall is dying a lot and at restore we are getting email storm about devices that are on other sites.

firewall team will have a replacement "soon".

In the meantime I guess I should add a depend (first hop) for all 2000+ devices in hosts.cfg file.

Is there another option with less editing?

Thanks for any suggestion!
