Bad Envelope FROM when using alias from different domain.
Hello,
I found a error in Pantheon Mail which breaks DMARC checks.
When I have account with alias from different domain created this way: username: [email protected] e-mail address: [email protected] e-mail alias: [email protected]
Pantheon mail is using wrong envelope-from, if I use one of aliases.
If I select to use mail [email protected] in new-mail dialog, it uses these values in headers: Envelope-From: [email protected] Body From: [email protected]
When I select [email protected] as sender, then it uses these values: Envelope-From: [email protected] Body From: [email protected]
In second case it can break DMARC verification check on recipient's side and e-mail will be quarantined/rejected (depends on policy for mydomain.com).
Envelope-From: and From: header should be aligned (from same domain).
