SMTP Settings & Requirements

To ensure secure and reliable email delivery, please use the following SMTP settings when integrating with ZatpatMail:

SMTP Server Details:

SettingValue
SMTP Hostsmtp.zatpatmail.com (or your actual host)
Port (SSL)465
Port (TLS)587
AuthenticationRequired (Username & Password)
TLS VersionOnly TLS v1.2 is supported

Lower versions of TLS (v1.0/v1.1) are not supported due to security concerns.

From Address Requirements:

The “From” email address used in your application must belong to a domain you own.
This domain must have:

  • A valid SPF record
  • DKIM signature
  • A verified DNS entry in your ZatpatMail account.
    Emails from unverified domains will be blocked or rejected.

Compatibility Help – We’ve Got You!

If your application, device, or server does not support the required encryption protocols (like TLS v1.2) or SMTP standards — don’t worry.

At an extra nominal cost, we provide an intermediate Mail Transfer Agent (MTA) which acts as a secure relay:

  • It accepts emails from your legacy system
  • Converts and relay them using ZatpatMail’s secure SMTP settings
  • Ensures compliance and delivery without you needing to change your source app

To request access to the relay server, contact our sales/support team.
