Sendgrid ignores spam complaints - IPs to block
« on: April 30, 2020, 10:20:06 am »
Sendgrid is an e-mail spam service and will not act on spam complaints to their abuse contact. You may have luck doing a full block of the following networks on your edge firewall:

149.72.0.0/16
168.245.0.0/17

Will continue to update if they spam from additional sources.
