I tried to forward an email that landed in my Gmail account to a 3rd party (through the Gmail web interface); should be simple enough...

However, I check my own emails immediately afterwards, and I had received the forwarded email, back in my Gmail account.

The headers of this email are something like this:

MIME-Version: 1.0
Received: by with HTTP; Fri, 25 May 2012 03:20:14 -0700 (PDT)
In-Reply-To: <[email protected]>
References: <[email protected]>
Date: Fri, 25 May 2012 11:20:14 +0100
Delivered-To: [email protected]
Message-ID: <CAGkfXuiZKGY9qut7Wu1m7F6pPLmoG9AbcvY3h6bfLLE+PQauSg@mail.gmail.com>
Subject: Fwd: AOL Postmaster Support Request #97257 Update
From: Me <[email protected]>
To: [email protected]

I'm puzzled.. the Delivered To header presumably means that the email was delivered to me (which it was) but why? The To header correctly shows my target.

Did I automatically get a copy of the email? Or have I (only) received the mail?

I tried forwarding the email on to another account of mine. I received the forwarded email in the target account, but also received a copy back in my Gmail account.

Not sure why I get the unnecessary copy sent back to me, nor how to stop it.

I normally use Gmail through a client (Outlook/Thunderbird); I'll try forwarding via the client and see what happens.

  • The copy of email you receive is marked a "read" or "unread" by default?

  • It was unread, IIRC.

The only way this all makes sense is that [email protected] has a setting which says "Forward all incoming mails to [email protected]"

One another possibility is that your message was not delivered and you received a new message in the same tread saying, "Message Delivery Failed" but you have not noticed that until now.

  • There definitely isn't a forwarding applied to the target email account. And the mail is categorically not a Message Delivery Failed one. I agree, these would make sense. As I said in the OP, I re-forwarded the same email to a different address and the same thing happened - both myself and the target received the email.

  • @CJM did you check your filters though to make sure you have nothing that would be sending your email to yourself again when you forward. Commented May 27, 2012 at 14:14
  • There are absolutely no filters/forwarding or other embellishments set up on either the sending or receiving accounts. It's baffling.
