Hi,
I have some vps via virmach (legit seller) but it seems like all the ip’s from colocrossing are blocked as system mails (root mails) cannot reach my mail here in mxroute.
Can Jarland confirm this?
I’m not blocking colocrossing specifically, but may be blocking IP ranges that have consistently presented issues at some point in time. This may be especially true of servers that try to send as root without valid hostnames, as we’ve had some users misconfigure their servers and try to forward emails from hostnames like “root@Ubuntu” to gmail and it doesn’t do anything other than negatively impact IP reputation as gmail won’t accept invalid senders. It may be possible that I’ve blocked yours specifically if that sounds like you. Feel free to message me an IP at chat.mxroute.com.
