Since 13.0.6 users are getting notification emails when logging in from new IPs, need to disable

Since 13.0.6 (may have been 13.0.5), with gitlab omnibus ee (level is core), users are getting email notifications when logging in from different IP’s.

Need to know where the settings for this are, as our vpn uses DHCP, they will likely get different IP’s every day, and possibly throughout the day if they actively login and out of the vpn.
