A discussion is ongoing about the behavior of mailing list mode in Discourse groups. Manfred_Bayer-Lemerz is requesting that mailing list mode for groups should include the option to receive emails for one’s own posts, similar to categories. This feature is currently available for categories but not for groups.
Fefrei clarifies that this issue arises because mailing list mode and watching topics have different behaviors, particularly in regards to receiving notifications for one’s own posts. Fefrei explains that when using public posts with mailing list mode, users can choose to receive emails for their own posts, but this option is not available for group messages.
Manfred_Bayer-Lemerz provides an example of how their community uses groups and the PM feature, highlighting the issue of not receiving emails for their own messages. Codinghorror expresses skepticism about the desirability of this behavior.
Agit suggests adding an option to activate this feature, citing the need to explain the differences between group and category behavior to non-technical users. This would allow users to choose whether to receive emails for their own posts in group discussions.
Continuing the discussion from Problem with mailing list mode for Groups:
No sorry this already working for categories and I don´t now why you are closing this one. There is already in Settings:
Where you can decide if you would like to get a mail for your own post or not! This works fine in categories but it is not working for groups!!
Hope you understand me now!
To slightly generalize this, I think this feature request boils down to a setting Notify me of my own posts when I'm watching a topic. I don’t think that makes a lot of sense, but on the other hand, I never understood the idea behind mailing list mode echoing your posts 
Another way to read this is a request to add an option to expand mailing list mode to messages.
This discrepancy occurs because watching every topic and having mailing list mode on behaves very, very similarly, but differs in the ability to have your own posts echoed – and mailing list mode doesn’t exist for messages.
Sorry, I still don’t understand. Can you provide a more specific example?
When using public posts, and mailing list mode is on:
When using group messages in a watched inbox:
This is basically the inverse of the old I don’t want to get notifications for my own (public) posts resentment: This is I do want to get notifications for my own (group) messages.
I will try. I am talking here about mailing list for groups NOT categories!
For categories it works fine and with the setting above described you can turn on or off if you want to get an mail for you own post or not.
For Groups it is not working. Let me explain how we are using a group.
We define a group with some members of our community.
We are using the PM (message) feature to send a message to all Members of the group
Either with the WEB Interface or vie e-mail (as a group can also have a Custom incoming email address)
And here you don’t get an E-Mail for your own message but this should also work!
Hope I made it clear now!
Per @fefrei’s answer, I don’t think what you are describing is a desirable or correct behavior.
But why not add a option for activating it, to not always explain to my discourse users that groups and categories work different in mailinglist mode. And to allow not so “techie” people (people that want to see the whole discussion in their email clients, even their answers) - we have a lot of them, because we are a “no tech forum” - to take part in discussions.
Sorry to bother again on this topic
