Re: [mailop] o2.pl / wp.pl
They publish postmas...@wp.pl as a contact address. Wirtualna Polska has a premium sender (Nadawca Premium) program where they require people sending bulk mail above a certain volume to pay them for inbound email access. I don't know what the volume limit is, but I suspect it is very low and that you are potentially hitting it. https://dlaprasy.wp.pl/pr/316310/wirtualna-polska-przedstawia-program-dla-nadawcow-masowej-korespondencji Assuming you're not in a position to pay for this access, you might want to nudge those subscribers to a mailbox environment that won't cost you extra money, i.e. Yahoo or Gmail.

Re: [mailop] Test software for ARC?
Such a check should be trivial to script with dkimpy: https://launchpad.net/dkimpy/ from dkim import ARC maildata = open('path/to/mailfile').read() print(ARC(maildata).verify()) This will return True if signature is valid and False if signature is invalid. To test multiple files in a directory just use glob and a loop.

You can validate DKIM and ARC of an email message with mailauth https://github.com/andris9/mailauth#command-line-usage (developed by myself) Regards, Andris Reinman > On 1.

[mailop] Test software for ARC?
I'm trying to troubleshoot a DKIM issue which is also ARC signed, so I'm not positive if alignment is an issue or not. Basically, routing is a mess. Office365 -> Office365 -> Office365 -> Barracuda filter -> Onsite Exchange -> Our server. Hoping there is a program to throw in raw emails and let me know, but I didn't really see anything.

Hello Ops, does anyone know what mail client probes(?) email connections with from= to=?
