Something that can help here is to set yor "Email whitelist" and "Inbound
gateway" settings correctly within your Google Admin Console...

Here we have one set of servers ("inbound") that receive email from the outside
world, and hence untrusted sources. A second set ("outbound") receive email
from local or trusted clients.

We list the outbound servers in the "Email whitelist" within our Gsuite Admin
Console, which makes their spam checking a little more lenient for messages
arriving from these servers.

We list the inbound servers in the "Inbound gateway" within out Gsuite Admin
Console, which lets Google do SPF etc checks against the IP address of the
server connecting to ours, rather than against the IP address of our own
inbound servers.

Rightly or wrongly we don't do SRS for messages passing through the inbound
servers: only for ones going out through the outbound servers (ie, trusted
sources) that need to use an RFC5321.MailFrom that isn't our own domain.

PS. Should we really be continuing to discuss this within a bug report thread?
It just feels wrong somehow...
