This has happened to me several times recently; has never happened until a couple of weeks ago.
From the https://mail.google.com/mail/ web-interface, Cc an alias on my server, which expands to, amongst other things, my gmail.com email address; a bounce is immediately received in the thread (apparently, gmail doesn't reject the bounces from the very same server from which some messages are rejected). Most likely cause: too many domain names from the mtr(8) output in the message.
Same for sending a similar message directly from my own server, directly to my gmail.com address, being in the Cc field: a bounce is received within my own server, no message is received at gmail. The bounce from such an experience is at the end of this message. I consider this a major outage: how many other valid semi-automated emails addressed to myself have been unfairly rejected by gmail on the SMTP level recently? I also now know why my gmail.com address has been unsubscribed from several mailing lists over this summer, citing excessive bouncing. My own mailserver wasn't even involved: <<## Delivered-To: mureninc@gmail.com Received: by 10.114.5.70 with SMTP id q6csp13073ldq; Tue, 10 Sep 2013 03:43:00 -0700 (PDT) X-Received: by 10.204.76.203 with SMTP id d11mr18914232bkk.3.1378809779724; Tue, 10 Sep 2013 03:42:59 -0700 (PDT) Return-Path: <lm-sensors-bounces@lm-sensors.org> Received: from flocki.atrpms.net (m.at.physik.fu-berlin.de.
