Incorrect From value when message sent using Gmail alias

[yojimbo274064400]

Incorrect From value when message sent using Gmail alias. To reproduce issue:

• setup Gmail account, for example John Smith <[email protected]>
• add alias of John Smith (Alias) <[email protected]>
• compose a new message
• select From field and then from drop down menu John Smith (Alias) <[email protected]>
• populated required fields and send message

What was expected: Recipient receives message from John Smith (Aliased) <[email protected]

What actually happens: Recipient receives message from John Smith (Alias) <[email protected]> ― note it is not from aliased email address

Is this a know issue?

@yojimbo274064400 I can not reproduce it 6.8.3381.46 with my GMail account.
The received mail shows as From the aliased address.

The recipient address ist at GMail or elsewhere?

My mail header says:

Content-Type: text/plain; charset=utf-8; format=flowed
Message-Id: <[email protected]>
From: [email protected]
To: L <[email protected]>

That is because Gmail corrects the From: address once they receive it. I've seen this before.

Not a bug in Vivaldi Mail.

Although sending using an alias can be done through Gmail's web site:

If that happens, GMail violates standards for SMTP/IMAP/POP3 mail transfer.

@DoctorG It's been a while since I've seen that occur, but it is Gmail...

They also ignore periods in a username. If e-mails are sent to example.address at gmail dot com and exampleaddress at gmail dot com, the recipient will receive both.

@DoctorG,

I wonder if the issue only occurs when authenticating via OAuth?

[yojimbo274064400]

@edwardp,

Reviewing the raw received message shows a header field X-Google-Original-From with a value of the alias address — perfectly ties in with your explanation for why this is not a bug.

@yojimbo274064400 Supected Google rewrites mail headers. BAD!
