Um... OK.. It's Late.. I'm not sure I understand what you mean.
Are you revering to those spammers who look for people connected to the net with
open smtp ports to spam to or from?
What do you mean by "I expect you want them to pull data instead of pushing it?

Yes everything is a trade off. I know there are ways to get around some of thes
e things, however since we are (at least for the moment) offering shell accts, I
needed something that I could use easily with them as well as pop3 for reading
mail.
Also, having the mail in the users directory makes space usage/quotas easier to
manage for me.
Speaking of which, I think you will like my directory scheme.
Nicole = /home/1/n/nic/nicole
terry = /home/2/t/ter/terry
lambert = /home/3/l/lam/lambert
home is the general mount point
the first number is a random number generated during acct creation (1-3).
the 2nd char is the 1st char of the username
the 3rd char is the 1st 3 char of the username
Then the user name.
This makes adding another filer easy via the possible 1/2/3 mount points and I
think 3 filers would be plenty for the forseable future, but more could easily b
e added via a weighted random generator. This rest is to prevent too many users
per directory.
If you can think of any additions or alternatives, please let me know.

They have both, but reccomend the sparc version. I also need to run the Netscap

Hmm Yea but the other stuff has a nice pretty interface and has been used by ot
her cable companies. Just like I have said about the needs of the FreeBSD pages
, the bosses want to see who else is using it, etc etc. So, I could push it and
if it works I'm OK. If it doesn't, I'm MUD. FreeBSD I know, trust and belive in
enough to be able to say BAH! we don't need Xbrand comercial UNIX or Billy Bloa
tware and feel safe.
I will look deeper however.
Thanks
