Bring any SMTP relay
Connect an SMTP service that is not represented by a dedicated Wodby provider, including hosted mail platforms and organization-managed relay servers.
Integration
Custom SMTP integrations on Wodby
Use Custom SMTP to connect any standards-compatible SMTP server to Wodby as a reusable outbound relay. Configure the upstream host, secure transport, port, and optional credentials once, then attach the integration to OpenSMTPD so application stacks can send mail without embedding relay settings in app code.
SMTP
Keep relay transport secure
Use mandatory STARTTLS or implicit TLS and override the standard relay port when the upstream server requires it.
Reuse one mail route
Store relay settings and optional credentials in one integration, then attach the same outbound delivery path wherever it is needed.
Supported workflows
How Custom SMTP fits into Wodby
Each supported integration kind maps Custom SMTP into a specific part of the delivery workflow, whether that means pulling source code, running pipelines, relaying email, connecting managed services, or injecting provider credentials into workloads.
SMTP
Custom SMTP
Connect OpenSMTPD to any standards-compatible upstream SMTP server and reuse that relay configuration across Wodby application stacks.
- Set the upstream relay hostname, with port 587 and mandatory STARTTLS used by default.
- Choose implicit TLS for servers that require SMTPS, commonly on port 465, and add credentials only when the relay requires authentication.
- Attach the integration to OpenSMTPD so applications can send internally on port 25 while OpenSMTPD handles upstream delivery.

Stack fit
Stacks that commonly pair with Custom SMTP
Wodby does not treat integrations as isolated setup screens. They become part of stack delivery, so the strongest matches are the stacks where this provider solves a repeated operational problem.
OpenSMTPD
Stack
SMTP server stack that can relay mail directly or integrate with third-party delivery providers for reliable sending.
OpenSMTPD is the direct stack match: applications send mail to it internally, and it forwards messages through the configured Custom SMTP relay.
