Basic explanation about SMTP
SMTP (Simple Mail Transfer Protocol) is a communication protocol used for sending and receiving email messages over the internet. When an email message is sent, it is first sent to an SMTP server, which then relays it to the recipient’s email server.
How SMTP uses encription
SMTP with TLS (Transport Layer Security) is a secure version of SMTP that uses encryption to protect the contents of email messages. When you use SMTP with TLS, your email messages are encrypted as they are sent from your email client to the SMTP server, and then again as they are sent from the SMTP server to the recipient’s email server. This encryption helps to protect your email messages from being intercepted and read by unauthorized parties.
Floatingcloud private email servers are currently flexible and allow nonencrypted connection as well as TLS.
On the other hand, unencrypted SMTP does not use encryption to protect the contents of email messages. This means that anyone who is able to intercept the email messages (such as a hacker or someone on the same public Wi-Fi network) can read the contents of the message.
If you insist on TLS encryption many emails will not be delivered
If you enable only TLS for your SMTP server, it may not be able to send and receive email from many other servers that do not support encrypted connections. This is because many email servers still use unencrypted SMTP. For example, some older email servers may not support encrypted connections, and some servers may not have TLS enabled by default.
Therefore, it’s important to ensure that your SMTP server supports both encrypted and unencrypted connections. This will allow your server to send and receive email from a wide range of servers, including those that do not support encrypted connections.
In summary, SMTP with TLS is a secure version of SMTP that uses encryption to protect the contents of email messages. However, if you enable only TLS for your SMTP server, it may not be able to send and receive email from many other servers that still use unencrypted SMTP. Therefore, it’s important to ensure that your SMTP server supports both encrypted and unencrypted connections to ensure reliable email communication.
GDPR and SMTP Encryption
The General Data Protection Regulation (GDPR) is a data protection law that regulates the processing of personal data within the European Union (EU). The law requires that organizations take appropriate measures to protect the personal data of EU citizens.
When it comes to email communication, sending personal data via unencrypted SMTP can put the data at risk of being intercepted by unauthorized parties. This means that if your organization is sending personal data via email using unencrypted SMTP, you may not be in compliance with GDPR. So if you send private information using a flexible server that allows both TLS encryption ans unencrypted, you are liable and might be fined and sued if the recipient does not use TLS.
On the other hand, SMTP with TLS provides encryption that can help protect personal data sent via email. By using SMTP with TLS, you can ensure that personal data is protected from interception by unauthorized parties, reducing the risk of non-compliance with GDPR.

It’s important to note that using SMTP with TLS alone may not be sufficient to comply with GDPR. Organizations must also take other measures to protect personal data, such as implementing appropriate data security measures and ensuring that personal data is processed lawfully and transparently.
In summary, SMTP with TLS can help organizations comply with GDPR by providing encryption that helps protect personal data sent via email. However, using SMTP with TLS alone is not enough to comply with GDPR, and organizations must take other measures to protect personal data and ensure compliance.
