Fwd: ezmlm warning

[Timur Tabi]

I get a message list this every couple months or so.  I know that's
not frequent, but they always say the same thing:

<timur.tabi@gmail.com>:
User and password not set, continuing without authentication.
<timur.tabi@gmail.com> 74.125.197.26 failed after I sent the message.

Is it possible that gcc-help is trying to forward a spam or virus
email, and then blaming me when my server (gmail.com) rejects it?

Hi! This is the ezmlm program. I'm managing the
gcc-help@gcc.gnu.org mailing list.


Messages to you from the gcc-help mailing list seem to
have been bouncing. I've attached a copy of the first bounce
message I received.

If this message bounces too, I will send you a probe. If the probe bounces,
I will remove your address from the gcc-help mailing list,
without further notice.


I've kept a list of which messages from the gcc-help mailing list have
bounced from your address.

Copies of these messages may be in the archive.
To retrieve a set of messages 123-145 (a maximum of 100 per request),
send an empty message to:
   <gcc-help-get.123_145@gcc.gnu.org>

To receive a subject and author list for the last 100 or so messages,
send an empty message to:
   <gcc-help-index@gcc.gnu.org>

Here are the message numbers:

   62761

Hi. This is the qmail-send program at sourceware.org.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<timur.tabi@gmail.com>:
