User agent

Requests from SMTBot carry a user agent like this:

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.75 Safari/537.36 (compatible; SMTBot/1.0; +http://www.similartech.com/smtbot)

Device Detector identifies it with this pattern (a case-insensitive regular expression):

SMTBot

Anyone can put any name in a user agent. Where the operator publishes IP ranges, checking the request's address against them is the way to confirm a visit is genuine.

How Vireo counts SMTBot

Vireo keeps requests from SMTBot out of your pageviews and visitors and counts them on its bot report under Search engines, so you can see how much it left out rather than wonder why your server logs show more traffic.

Checked by running Vireo Analytics' own bot filter over SMTBot's user agents.
