[SunHELP] Mail Server Solution

[Vinay Bharel]

Hi all,

We have about 15,000 email accounts on our mail server(s). We are
currently using the passwd file for authentication. Provisioning is done
manually every day using some homegrown Perl/Shell scripts.

We are using Sendmail, Procmail as MDA and Cucipop.

All our accounts are stored in an Oracle database. We are already using
Steel Belted Radius to authenticate dial-up users using the Oracle db.

I think it's time that we automate email provisioning.

I was thinking of using a radius PAM module but that would still require
the user to be in the passwd file since both Sendmail and Cucipop need to 
lookup the UID and home directory in the passwd file.

Cost is a big factor because the company doen't want to spend too much
money on this.

Does anyone know of any mail server suite(s) ( SMTP / POP ) that can
authenticate users off of an Oracle db or Radius.

Any help would be greatly appreciated. TIA.
