One host sends just one email per day, the daily logwatch report. Here's /var/log/maillog entries from yesterday (hostnames are changed to make designations in this conversation more intuitive):
Mar 12 04:02:18 srchost sendmail[27151]: t2C82Bjr027151: from=root, size=2485, class=0, nrcpts=1, msgid=201503120802.t2C82Bjr027151@localhost.localdomain, relay=root@localhost Mar 12 04:02:19 srchost sendmail[27383]: t2C82IiB027383: from=root@localhost.localdomain, size=2756, class=0, nrcpts=1, msgid=201503120802.t2C82Bjr027151@localhost.localdomain, proto=ESMTP, daemon=MTA, relay=srchost [127.0.0.1] Mar 12 04:02:19 srchost sendmail[27151]: t2C82Bjr027151: to=recip@dest, ctladdr=root (0/0), delay=00:00:08, xdelay=00:00:01, mailer=relay, pri=32485, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (t2C82IiB027383 Message accepted for delivery)
First email is sent locally to root.
I see that it's sent *from* root. Where does it say it's sent *to* root?

Root I guess forwards through an alias so it resends to target.
/etc/logwatch.conf is configured to send to recip@dest.com, so no aliasing and no resending.
My major concern is accuracy. I mean, there's not much sense in using logwatch if what it's telling me is wrong.
I'm guessing it simply parses the message sent lines. Whether or not treating locally delivered emails is correct or not - I'm inclined to think it is. Either way it would probably be difficult to exclude it
- and then you would never be able to track locally sent emails.

Tracking where/how emails are sent would be done in maillog, not in logwatch.
I'd disagree. If one email is sent, saying two are sent is not correct. If one email is sent with one recipient, the total number of recipients is one. If I hold up two fingers and ask someone how many fingers I'm holding up and she says "four", that too is incorrect.
Yes, it might be difficult to machine-parse the maillog, but then the software-- here logwatch-- should either be fixed or its data described accurately (and hopefully too, meaningfully). It shouldn't post erroneous data.
