[BlueOnyx:18983] Email issues

[Gregg K]

Hello,
I don't know if this has anything to do with the issues we are having
lately, but today I noticed that on one  of my servers, I'm not able to get
any email.  The configurations seem to be all wrong.
It's looking for /etc/aliases, and I know that the aliases are at
/etc/mail/aliases
I also noticed something strange when logging on to the system.  Usually
after you SU to root, you get: root at servername admin
I'm getting just bash-4.1
In my email logs I get these
Jan 13 15:30:02 main sendmail[7524]: NOQUEUE: SYSERR(root): QueueDirectory
(Q) option must be set
Jan 13 15:30:07 main dovecot: pop3-login: Fatal: Couldn't parse private
ssl_key: error:0906D06C:PEM routines:PEM_read_bio:no start line: Expecting:
ANY PRIVATE KEY
Jan 13 15:30:07 main dovecot: master: Error: service(pop3-login): command
startup failed, throttling for 60 secs
Jan 13 15:30:07 main dovecot: imap-login: Fatal: Couldn't parse private
ssl_key: error:0906D06C:PEM routines:PEM_read_bio:no start line: Expecting:
ANY PRIVATE KEY

I get those errors repeatedly.
How can I reinstall my whole sendmail package?  Something is definitely
wrong here.
