DISCUSS INTEGRATION →How Dedicated SMTP Relay Works
A straightforward outbound email flow that integrates your existing mail server with managed relay infrastructure.
Your Mail Server
Your mail server or business application submits outgoing email to the configured SMTP relay endpoint.
SaadWebId SMTP Relay
The relay processes authenticated sending requests and applies configured security, filtering and routing controls.
Recipient Mail Server
Messages are transmitted to destination mail servers, subject to recipient acceptance, delivery policies, and network conditions.
Important:
An SMTP relay helps manage outbound delivery,
but final inbox placement depends on sender
reputation, message content, authentication,
and recipient filtering policies.
Security & Email Deliverability
A reliable SMTP relay infrastructure requires more than a server capable of forwarding messages.
Authentication, secure transport, domain configuration, traffic monitoring, and sending controls all contribute to a more manageable outbound email environment.
SaadWebId helps organizations configure and review these components based on their mail systems and selected service requirements.

Frequently Asked Questions
Answers to common questions about SMTP relay configuration, security, email delivery and service packages.
What is a Dedicated SMTP Relay?
An SMTP relay is a service that forwards
outgoing email from a mail server or
business application to external recipient
mail servers. Dedicated configurations
may provide separately allocated resources
depending on the agreed service package.
Can SMTP Relay be used with Zimbra?
Yes. Zimbra can route outbound messages
through an SMTP relay using supported
relayhost settings, SMTP authentication,
and configured network ports.
Can I use SMTP Relay when port 25 is blocked?
In many environments, an SMTP relay can
be accessed over an alternative supported
submission port. This depends on the
relay endpoint, provider restrictions,
and authentication settings.
Does SMTP Relay support SPF, DKIM and DMARC?
Yes. SaadWebId supports SPF, DKIM and
DMARC configuration requirements.
Correct authentication depends on DNS
records, signing configuration, and
sender domain alignment.
Will SMTP Relay guarantee inbox delivery?
No SMTP relay provider can guarantee
inbox placement. Deliverability depends
on IP and domain reputation, message
content, authentication, sending patterns
and recipient filtering rules.
Does SMTP Relay include spam and virus filtering?
Yes. SaadWebId SMTP Relay packages include
spam and virus filtering capabilities.
Specific filtering policies depend
on the service configuration.
What happens if a recipient server is temporarily unavailable?
Temporary delivery failures may be
handled through queue and retry mechanisms.
Retry behavior, retention and final delivery
depend on relay policies and SMTP responses
from recipient mail servers.
Can I request a custom SMTP Relay package?
Yes. You can submit a custom quotation
request when your sending domains,
email volume, message size, or infrastructure
requirements exceed the standard packages.
Is there a discount for annual subscriptions?
SaadWebId offers an annual subscription
promotion: pay for 11 months and receive
12 months of service, subject to
applicable terms.
