This is not a Postgres bug. I would say to please use an appropriate
channel but, uh, our mailing list maintainers don't really have a good
channel for reporting such problems :(

In any case you should disable SAV. It is well documented to cause
such problems and is likely to get you banned if you use it on a site
which receives any significant amount of email from one place (such as
Postgres lists!).

Fwiw the addresses used in the VERP are not blocked, they're
greylisted. I suspect that is a mistake and they shouldn't be but
there's nothing inherently wrong with it the way it is and your SAV
implementation is just broken. Arguably the very concept of SAV is
broken though.
