On premise SpamTitan appliance injecting IP routes

We recently migrated to a new firewall and most things were okay apart from email flow. There was a queue on SpamTitan which wouldn't release. When I checked the routing table, rather than using the default gateway it had been routing directly to the old firewall (rather than to the core L3 switch). The only way to fix it was to reboot the appliance. However, it's still bypassing the default gateway and going directly to the new firewall. The SpamTitan support guys couldn't see anything wrong with the appliance and suggested there was some dynamic routing going in. There isn't, it's just statically set everywhere.

The setup is:

SpamTitan (192.168.1.6)-->Core L3 Switch (192.168.1.50)-->Firewall (192.168.1.70)

Routing table image as I can't format it in the text below

The current routing table is this:

Internet: Destination Gateway Flags Netif default 192.168.1.50 UGS em0 1.68.169.119 192.168.1.70 UGHD em0 1.119.129.17 192.168.1.70 UGHD em0 1.186.104.237 192.168.1.70 UGHD em0

I tried to find out what the flags mean, but I couldn't find any explanation of what they mean in practice, just a copy and pasted definition of what they mean.

Day-to-day it causes no issue, but if I need to make changes at the core level, then the SpamTitan box is just going to ignore this (and possibly some other appliances)?

do the ips belongs to you or do know the owner?

The IPs are all under our control.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
