Which
POP-observing
Unix-hosted mail delivery agent (MDA) should I use?
... I'm starting to collect comparative data on these:
As reader Cem Celebiler rightly points out, among the capabilities
of most interest to ISPs are
- multiple domain support (with multiple IPs or single IPs)
- flexible authentication options (unix /etc/passwd, PAM,
LDAP, etc)
I'm planning to explain these aspects later in May.
[Explain protocols, related resources.]

Several authentication methods have been coded, including
native Unix,
Kerberos,
LDAP,
PAM,
Radius, TACACS, and native NT Domain authentication.
The account "cyrus" owns the message store.
Status as of the beginning of June 1999: support for mail spools in
home directories, shadow passwords, and PAM authentication.
Imminent: APOP, and perhaps virtual domains. IDS POP is GPLed.
NMS can authenticate against LDAP.
[See also MTA-related references.]
Sometimes I refer to Qualcomm's official
FAQ.
qpopper doesn't know about LDAP.
qpopper has its own Web page,
with useful mailing list, ...
qpopper reportedly can use APOP, MD5, ... My only experience
is in hacking in my own authentication; I don't yet know how
to use the distribution mechanisms.
SIMS can authenticate against LDAP.
