Short answer: ConfigServer closed on 31 August 2025, ending ConfigServer Mail Queues (cmq), MailScanner Front-End (MSFE) and Outgoing Spam Monitor (osm). The replacements are MegaWit Postmaster (Exim queue manager plus inbound anti-spam, outbound-spam detection and SPF/DKIM/DMARC in one panel, cPanel, Plesk and DirectAdmin), WHM's built-in Mail Queue Manager (free, queue only), Imunify Email (CloudLinux's mail-filtering add-on), hosted filtering services MailChannels (outbound) and SpamExperts / N-able Mail Assure (inbound), and the free Apache SpamAssassin + ClamAV that ship with cPanel.
Way to the Web Ltd., the company behind ConfigServer, closed on 31 August 2025. cmq was a free queue browser; MSFE (MailScanner Front-End) and osm (Outgoing Spam Monitor) were commercial and lost updates and licensing that day. For mail servers that means:
Sources: cPanel support, EuroVPS end-of-life notice.
What a replacement needs to cover: browsing and acting on the Exim queue (cmq), filtering inbound spam and viruses (MSFE), and catching compromised accounts and scripts sending spam (osm).

MegaWit Postmaster (MWP) is our product. It replaces cmq with a full Exim/Postfix queue manager, and MSFE and osm with inbound anti-spam and anti-virus, an inbound spam report with one-click "not spam", hard per-account sending limits, outbound content scanning that pinpoints the PHP script sending spam, a sender blacklist enforced in Exim, RBL/PTR checks, outbound sending-IP control and one-click SPF/DKIM/DMARC fixes. Hosting customers get their own spam folder, quarantine, allow/block lists and daily digest. Runs on cPanel/WHM, Plesk and DirectAdmin; $14.99/month per server.
Best for: hosts that want queue management and mail security on the server, without per-mailbox fees.
cPanel's own queue tool lists, delivers and deletes queued messages. It covers basic cmq tasks but nothing of MSFE or osm.
CloudLinux's mail-filtering add-on for hosting servers, covering inbound and outbound spam. A natural choice if you already run Imunify360.
Routes outgoing mail through MailChannels' relay, which filters spam before it leaves and protects your IP reputation. It does not manage the local queue.
Filters inbound mail in the cloud before it reaches your server, by changing the domain's MX records. Strong filtering, priced per domain or mailbox.
cPanel ships SpamAssassin and offers a ClamAV plugin. They filter inbound mail per account, but there is no central quarantine, no outbound spam detection and no queue tooling.
No. ConfigServer closed on 31 August 2025. cmq still lists the Exim queue, but it gets no updates or support; MailScanner Front-End (MSFE) and Outgoing Spam Monitor (osm) also lost updates and licensing that day.
MegaWit Postmaster replaces both on the server: a full Exim queue manager plus inbound anti-spam and anti-virus, outbound-spam detection that finds the sending script, per-account sending limits and SPF/DKIM/DMARC fixes, on cPanel, Plesk and DirectAdmin at one flat per-server price. Imunify Email is the CloudLinux option; MailChannels and SpamExperts / Mail Assure filter mail as hosted services.
Yes: cPanel's built-in WHM Mail Queue Manager handles basic queue tasks, and the exim command line (exim -bp, exiqgrep) covers the rest. For inbound filtering, cPanel ships Apache SpamAssassin and a ClamAV plugin. None of them replace MSFE's or osm's central quarantine and outbound-spam detection.
MegaWit Postmaster scans outbound mail, holds or refuses mail from accounts over their sending limit, and shows the PHP script that sent each message, so a compromised site can be fixed instead of just suspended.
MegaWit Postmaster installs with one command on cPanel/WHM, Plesk and DirectAdmin and adds its panel to each. WHM's Mail Queue Manager is cPanel only; hosted services such as MailChannels work with any server.
