FYI.

I strongly recommend that you do not use the "Subject" field when
filing emails.

In the past, it was standard practice for the Subject of emails sent
from mailing lists to include the mailing list name. For example, for
this mailing list, [SLE] was placed at the beginning of the Subject
field. However, this practice was discontinued as a spam
countermeasure. In other words, if [SLE] appears at the beginning of
the Subject field, recipients assume the email is from the mailing
list and open it.

Therefore, I recommend using more reliable fields in the email
headers. I use procmail for 1). virus scanning, 2). spam filtering, and
3). email filing of incoming messages, and my configuration looks like
this;

	:0 H

	* 9876543210^0 ^To:.*[email protected]
	* 9876543210^0 ^From:.*OPENSUSE-UPDATES
	* 9876543210^0 ^List-Id:.*updates.lists.opensuse.org
	mh/Linux/suse-updates/.

Best Regards & Good Night.
