MailMum for MSPs Running Mail for Clients

Managing mail security for multiple clients usually means juggling separate tools, separate lists, and separate reporting per client. MailMum’s account and server model maps directly onto how you already work.

How it fits your model

• Account = client, servers = their mail servers. Apply a baseline blacklist across a client account, then let individual mail servers add their own exceptions.
• Clean, isolated reporting. Hand a client a clear picture of what was blocked and why — without exposing any other client’s data.
• Role-gated admins and viewers per account, so client-side staff can be given visibility without full control, or vice versa.
• Analytics per server and per account — blocked-vs-passed traffic, hourly volume, and blacklist match counts — so you can show clients real numbers, not just “we’re handling it.”

Getting a client onboarded

Create an account for the client, add their mail server(s), and point each server’s RBL check at MailMum — see the MailMum documentation for the Postfix/Exim/etc. configuration steps. From there, baseline rules and per-server exceptions are managed entirely inside MailMum.
