Nick’s Review of Greenarrow Vs Smtp.Com

SMTP Services are an essential part of GreenArrow Engine, allowing users to send and receive emails efficiently. GreenArrow Engine provides three SMTP services: SMTP, SMTP2, and SMTP3. The SMTP service is responsible for receiving incoming SMTP traffic, including bounces and feedback loop complaints. SMTP2 and SMTP3 are used for relaying messages from SMTP clients.

Configuring the SMTP service is crucial for proper functioning. By default, the SMTP service is enabled and listens on port 25 of at least one publicly accessible IP address. However, users can specify the IP address and port for the SMTP service to listen on. The /var/hvmail/control/smtp.ipaddr file is used to specify the IP address, while the /var/hvmail/control/smtp.port file is used to set the port. Users can enable or disable SMTP AUTH, which is useful for authentication purposes.

The SMTP2 service offers several advantages compared to the SMTP service. It uses default ports that are less likely to be blocked by firewalls, making it easier to troubleshoot problems related to SMTP relaying. SimpleMH, a feature for handling mail injection, is enabled by default on the SMTP2 service. Users can configure the SMTP2 service by editing the /var/hvmail/control/smtp2 configuration file. The service can be enabled or disabled by setting the ENABLED variable to 0 or 1, respectively. IP address, port, and concurrency settings can also be adjusted according to user requirements.

Similar to SMTP2, the SMTP3 service can be configured using the /var/hvmail/control/smtp3 configuration file. All steps that mention SMTP2 should be replaced with SMTP3 in this case.

To authorize SMTP clients, GreenArrow Engine offers two methods: IP address and SMTP AUTH. IP addresses can be specified in the IPs Authorized to Relay document. SMTP AUTH allows clients to authenticate using a username and password. Users can enable or disable SMTP AUTH for each SMTP service individually.

In addition to SMTP services, the GreenArrow documentation covers a wide range of topics related to email delivery and management. Users can find information on the Engine, Marketing Studio, Inbox Monitor, and various configuration settings. There are also FAQs that address common issues and errors, as well as resources for email authentication, mail injection, delivering mail, handling bounces and spam complaints, reporting, event notification, server management and backups, APIs, and third-party integrations.

GreenArrow Engine provides a comprehensive set of tools and resources to ensure efficient email delivery and management. With its SMTP services and extensive documentation, users can confidently handle all aspects of their email operations.

SMTP Relay Service Integration is a feature provided by GreenArrow Engine, which allows users to send email through a SMTP relay service instead of sending email directly through their own IP addresses. This integration is useful for users who are migrating from a SMTP relay service to GreenArrow, want their email to be part of the shared IP pool of the relay service, or do not want to manage deliverability themselves.

To integrate with a SMTP relay service, users need to configure a “Relay Server” in the GreenArrow Engine web interface. This Relay Server VirtualMTA will contain the account information for the SMTP relay service. Once configured, users can choose the Relay Server as an option in the SimpleMH Mail Class config or in GreenArrow Studio’s Delivery Settings.

When it comes to handling bounces, it is preferred if the SMTP relay service can deliver or forward bounce messages to the original “Return-Path” of the email message. This allows bounce related processing, suppression, and reporting to work normally in GreenArrow. However, if the relay service does not provide this functionality, alternative methods such as internal suppression by the relay service or exporting and updating the bad addresses in the database can be used.

Similarly, for handling spam complaints, it is preferable if the SMTP relay service can forward the email that generated the complaint to a “spam complaint processing address” in GreenArrow Engine, or forward the ARF formatted spam complaint notification from the ISP. This enables spam complaint processing, suppression, and reporting in GreenArrow. If the relay service does not offer these options, alternative methods like internal suppression by the relay service or exporting and updating the spam complainers in the database can be used.

GreenArrow adds a “List-Unsubscribe” header to emails, which allows recipients to unsubscribe from the mailing list. It is preferred that the SMTP relay service either leaves the GreenArrow “List-Unsubscribe” header intact or replaces it with its own header and passes unsubscribe requests to GreenArrow. This ensures normal functioning of GreenArrow’s unsubscribe process. If the relay service inserts its own “List-Unsubscribe” header without passing unsubscribe data to GreenArrow, other methods such as internal suppression by the relay service or exporting and updating the unsubscribes in the database need to be implemented.

When using SMTP relay service suppression, there are some caveats to keep in mind. The list of suppressed addresses from the relay service needs to be synchronized with the user’s system before sending emails through another service or direct IP addresses. This ensures that suppressed addresses are not emailed again, which can lead to deliverability issues and legal implications. Additionally, the number of emails sent shown in GreenArrow may be higher than the number of emails sent by the relay service after suppression is applied, which can affect open and click rates. It is also important to note that once an address is suppressed, it cannot be resubscribed.

GreenArrow provides detailed integration guides for specific SMTP relay services like Amazon SES and Sendgrid. These guides provide step-by-step instructions on how to integrate GreenArrow with these services.

Overall, SMTP Relay Service Integration in GreenArrow offers users flexibility in managing their email delivery and allows them to leverage the benefits of SMTP relay services while benefiting from GreenArrow’s features and capabilities.
