IT infrastructure & sysadmin — Tampa Bay, FL
JLD‑LTS keeps your mail server, your Mac and Linux machines, your AWS account, and your network talking to each other — so your team stops noticing the infrastructure and gets back to work.
Free, no obligation
Missing or misconfigured email authentication is one of the most common — and invisible — reasons messages land in spam or bounce entirely. Send any email to the address below and we'll personally check your domain's setup and follow up with what we find.

What we handle
Moving off a dying on‑prem mail server, fixing broken SPF/DKIM/DMARC records, or untangling a spam blacklist — we set up Postfix, Dovecot, or a hosted alternative (Google Workspace, Microsoft 365, Amazon WorkMail, Zoho Mail) that your staff can actually rely on.
Patching, backups, user accounts, printer queues, permissions that made sense in 2019 and don't anymore. We manage mixed Mac and Linux fleets as one system, not two.
Right‑sized EC2 and S3 setups, VPC and security group cleanup, and a monthly bill you can explain to your accountant instead of just paying.
Firewalls, business Wi‑fi, and wired network design — built on Meraki, UniFi, Omada, and Aruba Instant On — plus VoIP phone systems on UniFi Talk.
Uptime checks, log review, and a phone number that a real person answers when something breaks at 6am — not a ticket queue.
How we work
Every migration, config change, and credential handoff gets written down in plain language and handed to you — not buried in one consultant's head. If we get hit by a bus, your business keeps running.

Common questions
Most engagements are quoted as a fixed scope before any work starts, not open-ended hourly billing. A one-time mail server migration is priced differently than ongoing monthly monitoring. The first call to scope the problem is free.
Yes. JLD-LTS supports remote and distributed teams nationwide, not just businesses in Tampa Bay. Mac and Linux administration, AWS architecture work, and mail server migrations can all be done remotely.
Usually it's oversized EC2 instances, unused EBS volumes or snapshots, S3 storage class misconfiguration, or untracked data transfer costs. A cost audit typically finds several of these at once, and right-sizing often cuts the bill significantly without changing what the infrastructure actually does.
In most cases, yes. It's usually missing or misconfigured SPF, DKIM, or DMARC records, a shared IP with a bad sending reputation, or an open relay. Fixing the DNS and sending configuration resolves it most of the time; if the IP reputation itself is beyond repair, migrating to a hosted alternative is usually faster than trying to rehabilitate it.
Every migration, config change, and credential handoff gets documented in a shared doc the client owns — not kept only in one consultant's head. That means the business isn't locked in or left stranded if the consultant is unreachable.
Send any email to email@checkauth.jldlts.com. We'll personally review your domain's SPF, DKIM, and DMARC authentication records — the most common cause of messages landing in spam or not arriving at all — and follow up directly with what's found. It's free and there's no obligation.
