Server Features

? The server Router can route messages on a per-domain and on a per-
account basis. The Router supports:
\- domain-level routing;
\- account aliasing;
\- foreign account aliasing.
? SIMS can handle accounts for multiple domains. The Multi-Domain
features use the Router and include:
\- direct mapping;
\- domain-based account name mapping;
\- "true multihoming" for systems with multiple IP addresses.
? SIMS supports dial-up and other client mail servers with registered
or virtual domains:
\- For systems with dynamic IP addresses: Unified Domain-Wide POP
Accounts can be created.
\- For systems with static IP addresses: SMTP feeds using RFC1985
(ETRN) are implemented.
? The SMTP subsystem has "anti-spam" features. The Server can:
\- stop strangers from using the server as a mail relay;
\- reject mail from the IP addresses of known offenders;
\- verify return-path validity to reject mail from "unreachable
sources";
\- reject mail from certain domains or from certain accounts;
\- use foreign RBL servers for blacklisting.
? SIMS accounts can include:
\- an auto-reply text (or a "vacation message").
\- a mailbox accessible using any POP3 client application;
\- a distribution list to "reflect" incoming messages to multiple
recipients;
\- a folder keeping messages as individual files (for automated mail
processing with third-party utilities);
? SIMS allows for remote password modifications and new mail
notifications.
? SIMS generates Return-Receipt messages when it delivers mail to
local accounts.
? User authentication is performed using OS Users&Groups information
and/or the SIMS own authentication.
? The SIMS mailbox format is identical to the UNIX mailbox format, and
if TCP/IP services are not available on the LAN, any mailer that can
read UNIX mailboxes directly (such as Eudora�) can also work with mail
accounts via File Sharing.
? SIMS supports both TCP and AppleTalk connections, so it can be used
with mailers that can work via an AppleTalk network (such as Claris�
Emailer). SIMS can be used on non-TCP networks, and it allows remote
users to check their mailboxes on the server when they are connected
to the server via an ARA connection.
? SIMS has a centralized System Log. The Server kernel and all its
components can generate Log records of any detailization level,
simplifying troubleshooting.
? Additional features include:
\- EOL tolerance
\- Relay Host name verification
\- Message-Id header insertion.
