Engagements are scoped in days, not quarters.
Postfix and Dovecot deployment, DKIM signing, queue monitoring, bounce handling and PTR alignment.
Authentication review across SPF, DKIM and DMARC, blacklist monitoring, and guidance on sender reputation.
Linux server hardening, firewall rules, automated backups, log shipping and alerting.
Internal tools that speak to SMTP relays, transactional email providers and webhooks.
Every engagement starts with a short written assessment, so you know what changed and why.
