Marketer from Email Geeks explains that the From header should be the client, and the return path should be the MTA. To handle replies (not bounces), a Reply-To header should be used.

Email marketer from Email Marketing Tips Blog talks about creating a comprehensive bounce processing strategy involving categorizing bounces (hard vs. soft), setting up alerts for high bounce rates, and implementing automated list cleaning procedures to ensure that bounces are managed effectively without impacting the original sender.

Email marketer from Email Authentication Blog explains setting up SPF, DKIM, and DMARC properly. Proper sender authentication helps improve deliverability and reduces the likelihood of emails being marked as spam or bouncing, which in turn reduces the need for bounce processing.

Email marketer from Email Provider Blog emphasizes the importance of maintaining a robust suppression list. By automatically adding bounced addresses to the suppression list, you reduce future bounce rates and maintain a cleaner sending reputation.

Email marketer from Mailgun shares that using a dedicated IP address and domain for transactional emails allows greater control over reputation and bounce handling. By managing your own infrastructure, you can configure bounce forwarding to a designated system without impacting your client's main domain.

Email marketer from Email Marketing Forum suggests developing a custom bounce processing script that analyzes bounce messages and automatically updates suppression lists. This system intercepts bounces, preventing them from reaching the client’s infrastructure.

Email marketer from EmailOnAcid details bounce management strategies like setting up a feedback loop and using a dedicated bounce processing script.

Email marketer from Reddit explains that creating a dedicated subdomain (e.g., bounces.yourdomain.com) for handling bounces isolates them from your main domain's reputation. Configure PowerMTA to send bounces to this subdomain.

Expert from Spamresource.com emphasizes the importance of managing the Return-Path header. Best practice involves setting up a dedicated subdomain for bounce processing. They explain that configuring PowerMTA to rewrite the Return-Path header ensures that bounces are sent to the designated subdomain, preventing client systems from receiving bounce messages directly. Additionally, detailed bounce analysis and categorization facilitate proactive list hygiene and sender reputation management.

Expert from Wordtothewise.com shares the advice of setting up a separate infrastructure for handling transactional emails to manage bounces more effectively. They explain that by creating a distinct setup using PowerMTA, you can configure unique Return-Path settings that direct bounces to your processing system. This keeps bounce data separate from the client's email system, while also giving you complete control over analyzing bounce data for improving email delivery strategies.

Expert from Email Geeks states that, as per RFCs, bounces should be delivered to the address in the envelope-from.

Documentation from SparkPost explains that using Variable Envelope Return Paths (VERP) allows you to associate each message with a specific return path. This helps in identifying the recipient that caused the bounce, facilitating automated bounce processing without exposing the client's actual return path.

Documentation from SparkPost mentions implementing List-Unsubscribe header along with proper handling of bounces and complaints. This way recipients have an easy way to opt-out, reducing the chances of bounces and complaints reaching the client's systems, as properly handled unsubscribe requests prevent future sends.

Documentation from SparkPost discusses utilizing the PowerMTA Management Console to configure bounce processing rules. It enables defining specific actions based on bounce codes, allowing you to redirect bounces to a dedicated mailbox or script for processing, thus preventing them from reaching the client's return-path.

Documentation from RFC Editor explains the importance of the Return-Path header in SMTP and how it is intended to receive bounce messages. It indirectly suggests that controlling this header (although not directly modifiable by the sender after submission) through proper configuration is essential to managing bounces.
