MailSolid
MailSolid checks the email security of your domains: whether they are set up correctly, whether anything changes, and who sends mail as you.
What it does
Section titled “What it does”MailSolid reads the public DNS of a domain (SPF, DKIM, DMARC and other checks), tells you what is wrong and gives you the exact records to fix it. After that it can watch the domain every day, read the DMARC reports that the large mailbox providers send, and use a real email to test how a message arrives.
MailSolid does not change your DNS: it gives you the record so you can copy it and paste it in your provider’s panel.
Each workspace is one business
Section titled “Each workspace is one business”Everything lives in a workspace: a business with its domains and its team. If you look after the email of several clients, the usual setup is one workspace per client, and you see them all together in All my clients.
The map of the console
Section titled “The map of the console”The sidebar gathers what you use every day.
| Section | What it is for |
|---|---|
| Home | Email overview: what needs attention and access to your domains. Missing results do not mean the domain is protected. |
| Domains | Search and filter the portfolio. Open a domain for its summary, changes, full diagnosis, DMARC and transport. |
| Hosted MTA-STS | Inspect policy and preparation status for a registered domain. Preparation does not activate infrastructure. |
| TLS report reception | Inspect destination, coverage and TLS reports. Missing reports do not prove successful delivery. |
| Alerts | Read each change, open its explanation and follow the evidence. Reading an alert does not change DNS or resolve its diagnosis. |
| Alert destinations | Owners and admins configure channels and their domain/group scope. |
| Domain health | Analyses a domain and gives you the verdict, the list of checks and the records to fix it. |
| Monitoring | Watches your domains every day and warns you when they change. |
| DMARC | Reads the reports sent by Google, Microsoft and others: who sends mail with your domain and whether it passes. |
| Real test | Gives you a temporary address; you send it an email and see how it arrived. |
| Email analysis | Upload a suspicious .eml file to analyse it. |
At the bottom you find Team, Plan and, for the owner and the admins, Public tools and Settings.
