The only issue is you have the x-sender thing as your long isp address. I
really kind of hate that about not running your own server on the domain,
as maybe I don't want everyone to know who my isp is off the email message.

Brent,
Please explain what the long x-sender string is and how I can get rid of
it. I don't see it on the messages that are returned to me.
Thanks.

Well, I don't know how to get rid of it without changing stuff in sendmail
to rewrite, but if I look up in the headers towards the top this is what it
says.

Mail header problems (was: Re: A Bunch of Questions)

[L. C. Robinson]

Well no one wants to see all the crap in the full headers, so
they are almost always turned off, unless there is some problem
with getting things through.  All kinds of virtual hosting and
masqing is so routine, that it doesn't even matter, really.  Your
ISP and the other mail relays are going to make sure that such
things are there anyway, and there's little you can do about it:
would you really want to have problems tracing the source of a
transport problem (and they do happen)?

Save yourself a lot of grief, and leave the mail header munging
stuff to the spammers.  You'll come to appreciate the extra info
with time, when it's needed.  Mostly, people will never notice,
unless you spam them.  If you do screw with the headers enough to
keep the spam filters from authenticating your stuff, you will
find various sites dropping and bouncing your mail.  Without such
filters the internet would quickly become unusable, with the
flood of trash.

So, is it possible to eliminate x-sender junk in your mail, if in fact you
run your own linux machine for you're domain and want no mention of any
other domain? Not everyone's mail has stuff like this in.

File names are stored in the directory structure. One file keeps names of
files in a directory. Where else do you think they reside? Hard drive
brackets? ;-)  In Unix everything is treated as "files"  including
hardware devices. Changing user ID numbers is trivial, one command 
line.

You need to rename the mailbox file manualy otherwise it won't belong to
the right owner as far as MTA is concerned. As far as I know, tools that
change the login name won't touch other things like mailboxes which is 
good.

If you change name only in the passwd file then yes, you do not need to
change the ownership of the home directory. However, you were 
talking about adduser command before usermod which would create a 
new user with different UID.

In any case you'll run into some issues if files in home diretory have
been customized for a particular user based on the login name and you
change the name so some handwork will be needed. X windows managers setup
is one of them.

As always, in Unix there is more than one way to do things.

Mailboxes are stored as files with the same name as the userid, at least
when using sendmail, so it may still be necessary to ensure that old mail
is preserved.

Re: A Bunch of Questions

[Brent Harding]

Cool, what sysadmin utils, where do I get them? All that's around now is
linuxconf, powerful, but not everything common by far, although it'll do
virtual pop automatically, and manage sendmail, a bear to do by hand.

On the contrary.  The filesystem does not store user names in the
directory structure.  Do "ls -ln" on your home dir, to see what
there really is.  Now do "id", to see what your id numbers are.
So when you change a username, it just changes the appropriate
mapping table (/etc/passwd), which file utilities like "ls" use.
Now, if you want to change user id numbers -- that can get hairy;
but there are automated ways to do that too.  And take my word

You could install linuxconf, and add/delete/modify users there too, easier

That won't take care of user's mailbox name and it's permissions nor it
will change the ownership of files in user's home dir as far as I know. At
least it won't work that way in all versions of Unix.

It should be in /usr/sbin, which might not be in your search path. In addition,
check that you have the shadow-utils rpm.

Dave,
Thanks for your information. However, my Redhat 7.1 sustem doesn't seem to
have a userdel command.
Thanks.

Have you tried
/usr/sbin/userdel

It must be there. Mine has it.

A safer way to move email is to stop mail daemon,

mv old-user-name new-user-name
chown new-user-name.new-user-name new-user-name

that is, change the ownership to new user otherwise you won't be able to
read it and restart the mail server. If you do it otherwise your cat
command could mess the email box if MTA was writing into it at the same
time.

Because you can lie about who you are. You're used to the Windows world where
anyone is free to do that all of the time. It's not really a good idea to allow
it though. For those companies and organizations who don't allow their users to
have root access, and who do care a lot about accountability, it's a good
constraint.

userdel old-user-name

>How do I stop a running daemon like fetchmail without rebooting?

killall fetchmail

cd /var/spool/mail
cat old-user-name >>new-user-name
rm old-user-name

Note the two right angle brackets before new-user-name in the cat command. This
is important. It means append. If you only put one of them there then existing
messages for new-user-name will be deleted as the whole file will be replaced.

A Bunch of Questions

[John J. Boyer]

Hello,
Well, I threw in the towel and just created a new user for the director
e-mail address, so I hope this goes through to the list. I wonder why
logging in with an address other than your login name is considered a
security risk.
Here are some other questions.
How do I delete a user?
How do I stop a running daemon like fetchmail without rebooting?
How can I transfer the messages in the inbox of one use to the inbox of
another?
Thanks.
John
