After waiting for a little while, the program terminated with the following output:
astrid@chungus infra gzip -vc result/nixos.img | ssh [email protected] -- bash -c 'gunzip -vc > /dev/sda'
[email protected]'s password:
77.8% -- replaced with stdout
What happened here?
The 77.8% bit is gunzip -v reporting that it finished decompressing the data to stdout and that the compression ratio was 77.8%... so this invocation may well have succeeded. Assuming, as rwmj points out, nothing else stomped on any of the written blocks.
Annoyingly, mailop.org list archives are member-only (free to join however).
Mail Archive has the content, though I never much liked their UI. Link to the first message of the most interesting (IMO) thread, though there were others around the same time: https://www.mail-archive.com/[email protected]/msg26087.html
edited to add: this was a general MS issue and not necessarily senders having spam/dns/domain issues, which I suppose it why it annoyed mailops so greatly! and of course the long tail of the wider internet
