Re: [dmarc-discuss] is that *really* valid

Even in this case Lastname is not a valid mailbox as it does not have a valid email address, even when you take into account the EAI update it should have been written as Lastname; Strictly speaking the ABNI allows display name with no double quotes as long you don't use any special characters

Re: [dmarc-discuss] is that *really* valid

Of cause From: Lastname, Firstname is a result of omitted backslash or double quotes. The fact is, according to RFC 5322 it's valid RFC5322.From field with 2 mailboxes in it and is not covered by RFC 7489. OpenDMARC implementation follows to known best practices noticed in RFC

[dmarc-discuss] is that *really* valid

Hello, I noticed a message with this RFC5322.From: From: Lastname, Firstname the message was authenticated by SPF and DKIM but opendmarc rejected finally. Is this From really valid? I would quote the displayname. If it's valid, I hit a bug in OpenDMARC. If it's invalid,
