Over 20 Features in One Affordable Package
Postmaster gives your organization a complete email infrastructure — no expensive hosted services, no per-mailbox fees.
Individual Email IDs
Assign professional addresses like [email protected] to every executive. Works with any email client they already use.
LAN-Wide Email Access
Every desktop on your LAN sends and receives email without a modem. One server handles everything for the entire network.
Multiple Domain Support
Manage all your organization's domains from a single installation. No limit on the number of domains you can add.
Multiple POP3 Accounts
Collect mail from personal POP3 accounts of users and deliver to their LAN inbox — no individual modem connections needed.
Universal Client Compatibility
Works with Outlook, Outlook Express, Thunderbird, Eudora, Netscape — any SMTP/POP3 client, including web browsers.
SMTP Gateway
Low-cost SMTP gateway for Lotus Notes, cc:Mail, MS Exchange, and other groupware — no need to replace existing systems.
Direct Delivery
Send email directly to the recipient's domain — critical when your ISP blocks relaying for custom domain addresses.
Department Alias Accounts
Create [email protected] that delivers to the whole team. Add or remove members without changing your published address.
Anti-Spam Filtering
Block spammers by email address or domain. Delete spam from the server before it even reaches your users' inboxes.
Browser-Based Admin
Manage all users and settings through any web browser. Create accounts fast using user templates — no local admin tool required.
Flexible Mail Schedules
Set day-specific dial schedules — more frequent checks on busy days, less on weekends. Full automation for always-on connections.
Priority-Based Sending
Trigger mail transfer when high-, medium-, or low-priority messages accumulate, or instantly with always-on connections.
Smart Autoresponder
Automated out-of-office replies that send only once per sender — no mailing list flooding or accidental reply storms.
Email Archiving
Archive all incoming and outgoing emails automatically. Configure archiving per-user for compliance and audit requirements.
Auto-Forwarding
Forward any account's mail to another local or internet address automatically — perfect for management oversight.
User Priority Queues
Messages from senior users or critical accounts are sent first — ensure executive communications never get stuck behind bulk mail.
Authenticated SMTP & POP3
Full support for authenticated protocols — ensures only authorised users on your network can send and receive email.
LDAP Address Book
A single company-wide address book shared by all users. No more individual updates — everyone always has the latest contacts.
Local-Only User Accounts
Configure specific users as local-only — they can email colleagues internally but cannot send to external internet addresses.
Anti-Virus Plug-in
Optional Mailscan for Postmaster scans all attachments for viruses at the gateway — stopping infections before they spread.
