According to the smtp logs, the problem seems to be that gmail is
rejecting viral email (unless it truly is a malformed non-viral
attachment which isn't likely). Some people believe viral email should
be sanitized and sent. Some don't. I generally agree with the latter
point of view, but many ISP's either just sanitize, or do nothing, so no
rejects.

And technically, "bounce" in this context is really "reject". Bounces
only happen if the receiving server initially accepts the email and then
decides not to send it on. This usually causes a MAILER-DAEMON message
to be sent to the sender from the receiving smtpd (which can cause huge
backscatter problems).
I just received a viral mail which was badly forged to look as if it comes
from
MAILER-DAEMON <[EMAIL PROTECTED]>. It _was_ however then
relayed by the lfs mailman.
Take a look at the originating header:
Received: from linuxfromscratch.org (host132-91.pool82107.interbusiness.it
[82.107.91.132])
by smtp.linuxfromscratch.org (Postfix) with ESMTP id BF44F27B7
for <[email protected]>;

From: "MAILER-DAEMON" <[EMAIL PROTECTED]>
The mail contained a FILE.SCR attachment of about 30k (a Windoze screen
saver
executable binary, if I'm not mistaken.) I never got a chance to check it
out though
because the mail provider blocked it.
So yes, it looks like Gmail or whatever other ISP people have been have
problems
with have legitimately been rejecting some mails from the lfs lists. But
personally
I have not received especially many spam or viral mails from the lfs lists.
(And surely
I should receive just as many as any other subscribers?)
SpamAssassin as of late has gotten stupid. It will be sorted as time
permits. Can gmail whitelist?
Maybe someone will need to look into that sooner than foreseen ;-(
