How to create username with "."

Hi

When i create username like this
"useradd user.name"
It shows the error message saying that the name contains
invalid characters

Is there any way to create username like that,

When i edit the /etc/useradd, /etc/shadow, /etc/group and
/etc/gshadow it
worked fine for me

one can try MailScanner with clamav
or AMAVIS.

You can also rely on spamassassin for spam filter

you need to update the setup rpm.

And I think your are using RHEL3 equivelent kernel.

Just update the rpm or use webmin will work.

It is bad idea to create such users.  For example, chown
command accepts 
argument of type "user.group".  You should stick
with letters and numbers.
