SUMMARY:Pop3 server for virtuals domains and users

-- 
Hi Managers,
      My earlier question was:
> I'm trying to configure a pop3 server, not the DEC one (MH subset), on
> an AlphaStation Dec-Unix 3.2D with C2 security.
>
> I use qpopper 2.1.4r3 with the C2 security patch and it works fine.
>
> But i have two DNS domains and i don't want to create users by the hand
> in each files of the C2 security even if i put '/bin/false' as the
> user's shell : I've not X11 to do this with XSysAdmin & XIsso.
>
> So i'm looking for a pop server using other files for authentification.
> Is the DEC's one a good pop server and easy to configure ?
> Is a better free pop server somewhere on the net ?
I've got partial answers to my problems:
> Qualcomm's popd version 2.2 is very good, and is avalaible at
> ftp://ftp.qualcomm.com/quest/unix/servers/popper It will allow you to 
> use another file for authentification.
But NOT both standard files (/etc/passwd, NIS,..) and extra file
(/etc/popauth)
Each user's uid in the extra file must exist in the passwd file.
=> Not easy to create a new pop user.

Not tested

Adduser perl script is avalaible at
ftp://alpha.pr1.k12.co.us/pub/mkuser/mkuser.pl
> the DEC popd server from mh package is a good one, but the mailbox of 
> the pop users created is not in the standard mail format and not to
> reuse.
> The password can only be change by the administrator
> A user cannot be a normal pop user (/etc/passwd) and a 'virtual' 
> pop user (pop auth file)
> popaka create a file with aliases to redirect mail to the 'pop' account
> like :  aaa:bbb_at_pop
> This line must be added to the sendmail :
>  Mpop,   P=/usr/lib/mh/spop, F=nsmFDM, S=10, R=20, A=pop $u
Maybe it works with another local mail deliver (procmail) ?
 
srb_at_cuci.nl (Stephen R. van den Berg) have made a new pop server,
cucipop,
which will be available on demand or on:
ftp://ftp.informatik.rwth-aachen.de/pub/packages/cucipop/cucipop.tar.gz
README extract:
> The Cubic Circle POP3 daemon. (v1.06 1996/08/19)
> 
> A fast and robust implementation of the RFC1939 POP3 protocol.
> It supports both BSD-type and SysV-type mailbox formats.
> Cucipop assumes that the mailbox it serves is not simultaneously
> accessed by a mailreader.  Concurrency and locking issues are handled
> graciously if they restrict themselves to the mail delivery agent
> (in case you were still looking for a fast and robust one, have a look
> at procmail :-).
> 
> Cucipop can run standalone (preferred, if you have a lot of readers) or
> can be started from inetd.
