If you use SPAM filtering that may block the cloud help desk IP addresses, we recommend whitelisting them to maintain delivery of notifications.
With hundreds of thousands of help desk accounts, some SPAM is likely to cause these IP's to be blacklisted from time to time. If you normally only get messages from your own help desk and not SPAM from other Spiceworks cloud help desks, it should be safe to permanently whitelist them. These IP addresses are only used for the cloud help desk.
The current addresses we use are: 167.89.74.79 167.89.75.142 167.89.82.157
