sendmail: write permition problem?

Hi,
I can not make my mail server (sendmail) work. First I thought
ssmtp (on sending side) is wrong, so I tried to send mail
manually, using telnet:

--------------------------------
obelix.somemydomain.com ~ # telnet mail.somemydomain.com 25
Trying 192.168.1.13...
Connected to mail.somemydomain.com.
Escape character is '^]'.
220 mail.somemydomain.com ESMTP Sendmail 8.14.0/8.14.0; Tue, 10 Nov 2009
19:57:31 GMT
HELO
501 5.0.0 HELO requires domain address
MAIL FROM:root [at] obelix
250 2.1.0 root [at] obelix Sender ok
RCPT TO:test [at] somemydomain
250 2.1.5 test [at] somemydomain Recipient ok
DATA
354 Enter mail, end with "." on a line by itself
Test message.
.
421 4.3.0 collect: Cannot write ./dfnAAJvV8n022567 (bfcommit, uid=0,
gid=209): Permission denied
Connection closed by foreign host.
obelix.somemydomain.com ~ #
--------------------------------

Q1: Why on my "HELO" sendmail does not respond with "250 OK"?

Q2: What does that "Cannot write ./dfnAAJvV8n022567" mean?
Maybe some write-permition on server side? But what/where?

--------------------------------
mail.somemydomain.com ~ # ls -al /var/spool
total 28
drwxr-xr-x 7 root root 4096 May 30 17:40 .
drwxr-xr-x 11 root root 4096 Nov 9 19:30 ..

drwxr-xr-x 2 mail root 4096 Apr 7 2009 mail
drwxr-xr-x 2 smmsp root 4096 Apr 24 2009 mqueue

mail.somemydomain.com ~ # more /etc/passwd | grep mail
mail:x:8:12:added by portage for mailbase:/var/spool/mail:/sbin/nologin
postmaster:x:14:1000:added by portage for
mailbase:/var/spool/mail:/sbin/nologin
smmsp:x:209:209:added by portage for
sendmail:/var/spool/mqueue:/sbin/nologin
mail.somemydomain.com ~ #
--------------------------------

I just installed sendmail on mail.somemydomain.com instead
of ssmtp, and did not change a lot, just included all my
server names in /etc/mail/local-host-names. What do I have
to do more???

The hostname in the HELO message needs to be included. It does not
unnecessarily need to be correct, but a lot of anti-spam measures will
reject it out of hand if the originating IP address does not have a PTR
address that matches it. So if you are connection from foo.example.com

HELO foo.example.com
