12 hours downtime in 9 months?? That seems like better than 99.5 percent uptime (99.8% was my estimate) to me.

The reason for our cancelling was because the gross failure of one of their biggest selling points (IMHO), which was the dictionary attack prevention. The company blocked about 30% of our mail traffic as spam each day, but since they didn't slow the dictionary attacks it didn't matter how much they stopped, the spammers were still harvesting our addresses for the spam (self perpetuating). The virus protection was o.k., but I got just as much out of Declude, with almost no administration as well. And finally, they said they maintained a 99.5 percent uptime, but over the last 9 months we have seen about 12 hours of downtime from them. In the end, we ditched Postini for Declude Virus (Looking to get Declude Spam soon), a well kept rules.ima, and some broad Far east blocking access lists on the router. I get very little spam since the change, and our maintenance is about 10 or 15 minutes per day dealing with Harvesters, and new spammers.
