You mean a rule where you can say [mail:received-from="domain:xyz.com" > move to > "Saved" folder] - and it happens, something like this? Honestly I did not check it but I guess they might handle it.

During my trials I didn't find any issue with their DKIM support. https://help.runbox.com/dkim-signing/ seems fine to me. You might want to ask if you are interested, unlike mailbox.org they do reply, and they reply promptly, and they reply as if they mean it.

Please do share here on HN if you happen to find something better. Cheers.
