Not sure if this is related to the bouncing email topic but I posted the details of this issue there.
It's not the same issue as SG not forwarding emails. SG is forwarding emails just fine for me.
It's about SG not accepting emails forwarded to SG.
If this is a related issue as "0sg.net bouncing for bad reverse lookups?", I apologize for reposting.
Emails auto-forwarded from my gmail address to my SG address are being rejected by SG with a TLS error as of 2/24/2023.
