SMTP Settings & Requirements
To ensure secure and reliable email delivery, please use the following SMTP settings when integrating with ZatpatMail:
SMTP Server Details:
| Setting | Value |
|---|---|
| SMTP Host | smtp.zatpatmail.com (or your actual host) |
| Port (SSL) | 465 |
| Port (TLS) | 587 |
| Authentication | Required (Username & Password) |
| TLS Version | Only 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.
