I was looking at similar setup for a friend of mine.
The setup was going to be a web based email system.
No POP3 or any other kind of access.
My experiences:
1) Do not create users on the system.
Adding users when you above 10K users takes an
awful long time (>1 min each).
I tried a simple perl script to add 10K users
took about a day and half.
But deleting them got done overnight.
I haven't tried NIS
I am running FreeBSD CURRENT-3.0
2) Since I decided to use qmail for the mail server,
I am looking at two options:
a) use the .qmail-user type mapping for these virtual users
or
b) hack qmail to lookup a mysql database if the users
are not regular users.
I tested this hack out and was satisfied.
I think by not creating users on the system, I will be
reducing a whole lot (if not all) of security holes.
Any suggestions/comments welcome...
Implemnting the CGI for adding users is as simple as
creating a dir and a file (for case a) and inserting
a couple of records in the database (for case b).
I am still scratching my head of how to implement
the mail reading/sending front end (especially MIME stuff)...
I could definitely use some help at this mailbox format.
Any one has more suggestions please post... ;)
