Sendmail vs. OutboundSMTP

The Sentrion platform developed by Sendmail is designed to accommodate complex and large-scale environments, and we also provide a segment of this offering as open-source. While it may not cater to every user's requirements, Sentrion stands out as an ideal option for those utilizing open-source email solutions within extensive and intricate systems, as it can effectively support long-term messaging strategies that include virtualization, consolidation, and cloud migration. A critical component of email security is the Domain Keys Identified Mail (DKIM) standard, which allows senders to digitally sign their communications, enabling recipients to authenticate the legitimacy of the messages and confirm they have not been altered. This authentication mechanism allows recipients to trace the email's origin back to the sender's domain, ensuring confidence in the message's integrity. Through the application of cryptography, DKIM presents a well-regarded method for mitigating email fraud, thus protecting an organization's reputation and brand while keeping implementation expenses within reach. Given the rising incidence of email-based threats, integrating DKIM into your security framework can be an essential measure to enhance your email defenses, ultimately fostering a safer communication environment for users.

Utilizing DKIM signing significantly increases the chances of your emails being delivered directly to the inboxes of major providers like Gmail and Office365. Our service, backed by numerous servers across the USA and Europe, ensures that your email delivery is both reliable and efficient.
