Mimecast Deployment in Plymouth
Deploying Mimecast for Plymouth organisations, where the mail routing change is the risky part. Redirecting your domain's mail through a new gateway can bounce messages or loop them between systems if the receiving side is not adjusted at the same time — and mail lost during a cutover is difficult to recover and impossible to hide.
Why this comes up
The problem
Routing was changed before the mail platform was configured to accept from the new gateway.
What you get
What we deliver
- Inbound and outbound routing changed in the correct order, not simultaneously
- Mail platform configured to accept from the gateway before records are switched
- Connectors restricted so mail cannot bypass the gateway or loop back
- Record lifetimes shortened in advance so the change can be reversed quickly
- Authentication records updated to include the new sending path
- Delivery verified in both directions before the old route is removed

Mimecast Deployment in Plymouth — common questions
- What causes a mail loop?
- Two systems each believing the other is the destination. If the gateway routes to your mail platform while the platform still routes outward to the gateway, messages circulate until something drops them — which is both invisible to senders and awkward to unpick.
- Why shorten record lifetimes first?
- So the change propagates and can be reversed quickly. Records cached for hours mean a problem discovered at ten in the morning persists into the afternoon, whereas short lifetimes set a day beforehand reduce that to minutes.
- Should connectors be restricted?
- Yes, or the gateway becomes optional. Leaving your mail platform willing to accept from anywhere means attackers can deliver directly and bypass the filtering entirely, so restricting acceptance to the gateway is what makes the deployment meaningful.
- What about authentication records?
- They need updating to include the new sending path, or your outbound mail starts failing checks. This is a common oversight during gateway changes, and the effect — legitimate mail landing in spam — appears gradually rather than immediately.
- Do you work with businesses across Devon?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South West, including Plymouth and the surrounding Devon area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Plymouth businesses do you usually work with?
- Marine and defence supply chain systems where security accreditation is a precondition rather than a differentiator. Beyond that we work across Marine & Defence, Manufacturing, Healthcare, Higher Education and Tourism.
- Do you cover the areas around Plymouth?
- Yes — we work throughout South West, including Exeter, Truro, Bristol. Plymouth is an urban area of roughly 260,000+, and we take on work across the wider Devon region rather than the city boundary alone.
