Set SPF record to new CARP IP
Open, HighPublic

Description

I've created a new mailbox to manage potential partnerships.

I've noticed mail is considered as SOFTFAIL because we changed two different ways the routing:

  • before OSPF, Hervil used a DIRECT connection for SMTP traffic
  • default router was router-001 (51.255.124.8), it's now router-002/-003 (51.68.252.230)

In roles/dns/knot/files/zones/nasqueron.org.zone we've:

nasqueron.org. 86400 IN SPF "v=spf1 +mx +ip4:51.255.124.8 +ip6:2001:41d0:303:d971:0:0:517e:c0de ?ptr ~all"

  • 51.255.124.8 is the router-001 IP
  • 51.68.252.230 is the VIP of router-002/router-003

Mail current SPF status: SOFTFAIL with IP 51.68.252.230

We should either:

  • Allow mail traffic to directly be sent by Hervil (+mx block already in SPF record)
  • Update record to also include the new VIP address

Best short-term solution, to allow mail from Docker services too, is to allow the new router IP.

We also need to document what to do when we create a new router.
