gmail.com 550-5.7.1 refusing mtr(8) output; other excessive bounces

22 Sep 2013

      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:
