Till you mentioned about it I've ignored the existence of
/usr/libexec/mail.local. :-) I'm a new to OpenBSD. Is it some kind of
procmail's alike functionality?
My configuration is almost the after-install defaults. There's just
a /root/.forward created at install time pointing to my user. I thought
about it, I tried removing that .forward file and removing aliases I'd
added later and logged in *only* root user I sent email from root to root
to find out if some variable set in my ~/.kshrc or ~/.profile could be
interfering.
I tried modifying the comsat line in inetd.conf, using just udp4,
removing the ip limit prefix, etc. I've tried installing procmail
(telling smtpd to use it). I did some tests stopping /etc/rc.d/inetd
and running inetd -d form the command line.
With the default inetd.conf, after sending a mail to myself:
# inetd -d
ADD: 127.0.0.1:comsat proto=udp, wait.max=1.256 user:group=root:wheel builtin=0
server=/usr/libexec/comsat
ADD: ::1:comsat proto=udp6, wait.max=1.256 user:group=root:wheel builtin=0
server=/usr/libexec/comsat
ADD: daytime proto=tcp, wait.max=0.256 user:group=root:wheel
builtin=1959e0e08630 server=internal
ADD: daytime proto=tcp6, wait.max=0.256 user:group=root:wheel
builtin=1959e0e08630 server=internal
someone wants comsat
14937 execv /usr/libexec/comsat
The last two lines appeared right after sending the email. I understand
(in my ignorance) that means inetd *receives* the notification (from
mail.local?). And the following is what netstat shows:
# netstat -a -p udp
Active Internet connections (including servers)
Proto Recv-Q Send-Q Local Address Foreign Address (state)
udp 0 0 localhost.biff *.*
udp 0 0 *.syslog *.*
Active Internet connections (including servers)
Proto Recv-Q Send-Q Local Address Foreign Address (state)
udp6 0 0 localhost.biff *.*
udp6 0 0 *.syslog *.*
And that's all that came to my mind (I've tried also opening and closing
my living room's window several times :-)).
I know biff isn't a big concern but I insisted because I thought it
could be a symptom of some other more important issue.

PLEASE, LET'S PRESERVE GOOD EMAIL PRACTICES
- Use plain text (no HTML please).
- Separate paragraphs with empty lines.
- Use hard wrapped lines at no more than 72 columns.
- Avoid top-posting.
- You'll find the above easy to accomplish by using a decent email
client (i.e. Thunderbird, Claws mail, Mutt).
