Workgroup Mailer
Question: What is workgroup_mailer? Why does Kavi put this on the Return Path of email originating from the system?
Email originating from a user's email client typically looks like this:
Return Path - jdoe@yahoo.com
From - jdoe@yahoo.com
All application email originating from inside groups uses this
standard:
Return Path - workgroup_mailer@domain
From - jdoe@yahoo.com
Here are three of the reasons for this:
1) The domain of the Return Path must match the domain that the email was sent from. If they don't match, many receiving servers will bounce it because it could be a possible spam with a forged header. This is a best practice to improve performance and to keep the system in compliance with spam guidelines.
2) Another reason it comes from workgroup_mailer is because the communication flow is complex and oftentimes there needs to be a distinction between system-generated and individual-generated email so that follow-up communication is properly routed, shared, etc.
3) Out-of-Office auto-responders also come here. Auto-responder email is low priority, which is why it's not sent to listmaster or some other more useful address that is needed for technical support.
