Fix Cloud VPS and Toolforge mail servers to work with the modern internet
Open, MediumPublic

Description

The Cloud Services environment provides two separate SMTP related services: outbound mail sending for all Cloud VPS hosts via the mx-out0{1,2}.wmflabs.org hosts, and inbound/outbound mail for Toolforge via the mail.tools.wmflabs.org service.

Both sets of mail servers have had a long list of historic issues related to modern internet practices of validating message origins/senders to combat spam. Historically these issues have been addressed (or not) on an ad hoc basis as active issues arise. As is often the case with this approach to maintenance of shared systems, once the active event is resolved (or the reporter gives up) the follow up tasks linger and rot in the global backlog. It feels like it is time to actually bundle these tasks together along with a bit of purposeful design to try and dig us out of this tech debt.
