SMTP & DNS Configuration
Get SPF, DKIM, DMARC, MX, and MTA-STS right.
Email DNS is a stack of overlapping standards — SPF, DKIM, DMARC, MX, MTA-STS, TLS-RPT, BIMI — and getting any one wrong breaks deliverability. We configure all of them correctly for your sending providers and document them for handover.
Includes SMTP relay configuration for transactional senders and application servers.
Common problems
- SPF record exceeding 10 DNS lookups
- DKIM keys not rotated in years
- DMARC published as p=none with no monitoring
- SMTP relay sending without proper auth or alignment
What's included
- SPF flattening or restructuring
- DKIM key generation and rotation strategy
- DMARC enforcement plan (none → quarantine → reject)
- MX, MTA-STS, TLS-RPT configuration
- SMTP relay configuration
- Documented DNS for handover
