What is Linode SMTP blocked?

SMTP (Simple Mail Transfer Protocol) is a communication protocol that allows email messages to be sent and received over the internet.

Linode may occasionally restrict SMTP communication from its servers in order to prevent spam and abuse. This implies that unless we take certain actions to unblock SMTP traffic, we will be unable to send email messages using the Linode server.

Solution to Linode SMTP blocked?

• Configure the email server to utilize a different port for SMTP transmission than port 25, such as port 587.
• Configure the email server to use SMTP authentication to validate the sender’s identity.
• Set up SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records for the domain to prevent spam detection.
  Contact Linode support to request that SMTP traffic for the server be unblocked.
