I've never seen one that informed me of a mail I actually wanted to
read, but I wouldn't say in general it's *always* safe to ignore them
all. Sometimes it could be a problem with your mail server. As a gmail
user, you can probably assume that bounces are due to gmail policies,
not due to their servers being down.

You can look at the bounce message to see the reason. For the recent
example it said this:

Remote host said: 552-5.7.0 This message was blocked because its
content presents a potential
552-5.7.0 security issue. Please visit
552-5.7.0  https://support.google.com/mail/?p=BlockedMessage to review our
552 5.7.0 message content and attachment content guidelines.
j10-v6si6866809pgq.503 - gsmtp

That seems pretty clear it was intentionally rejected by gmail, and so
if you trust google to filter your mail, you can ignore it.

If you want to know what you missed you can send an email to
gcc-index@gcc.gnu.org and look for the message ID given in the bounce
notification. If the subject line looks like spam, ignore it. But I
don't bother doing that.
