sendmail probs on Mandrake

I have installed sendmail from source on my Mandrake9.1 box. I had a few
probs getting it to build, but fixed them fine. Sendmail runs, but i get
two errors now:

1) when trying to send a mail, I get the following message:
"can not chdir(/var/spool/clientmqueue/): Permission denied Program mode
requires special privileges, e.g., root or TrustedUser."

2) when receiving mail, I get:
"erg.abdn.ac.uk... Unrecognized host name erg.abdn.ac.uk."
I test this by telneting to sendmail, and typing
"mail from (E-Mail Removed)"

does anybody know how to fix either of these?
Cheers

Well what are the permissions of the directory?
You need to have sendmail run suid root.

It is having trouble resolving the name. If youdo
ping erg.abdn.ac.uk
on that machine do you get an answer?

The ownership is set to mail:mail and the permissions are 770

There is no problems with the host, ping works for ipv4 and ipv6

group smmsp

From ${source}/sendmail/SECURITY:

sendmail must be a set-group-ID (default group: smmsp, recommended
gid: 25) program to allow for queueing mail in a group-writable
directory. Two .cf files are required: sendmail.cf for the daemon
and submit.cf for the submission program. The following permissions
should be used:

-r-xr-sr-x root smmsp ... /PATH/TO/sendmail
drwxrwx--- smmsp smmsp ... /var/spool/clientmqueue
drwx------ root wheel ... /var/spool/mqueue
-r--r--r-- root wheel ... /etc/mail/sendmail.cf
-r--r--r-- root wheel ... /etc/mail/submit.cf

[Notice: On some OS "wheel" is not used but "bin" or "root" instead,
however, this is not important here.]

That is, the owner of sendmail is root, the group is smmsp, and
the binary is set-group-ID. The client mail queue is owned by
smmsp with group smmsp and is group writable. The client mail
queue directory must be writable by smmsp, but it must not be
accessible for others. That is, do not use world read or execute
permissions. ...

What you typed is not an SMTP dialog.

That is no longer true since 8.12.x. The sendmail binary must be sgid smmsp.
