When new user added to group, email alert sending?

There is an email sending when new user added to site groups. It is sending custom email format "A new user had been added to XXX Section group of the Communities, the user's name is Matthew . The Member # of the user is 3493100". I don't understand how this is happen. Our customer center and sharepoint admin开发者_Go百科 only getting these emails. Now they want to their id from emails sending list. I think my previous colleague written this task.

How can I find this program or feature or event to remove email id? Please need help.

It sounds like it you have automatic group access turned on.

You can disable it by going to the group:

Site Actions -> Site Settings -> People and groups -> Select the group -> Settings -> Group Settings

Then under "Membership Requests" turn off auto accept requests, or clear the email.

The other option is to remove the access request email

Site Actions -> Site Settings -> Site permissions -> Manage access requests

Remove the email or the options from the menu

Manage alerts On the Site Settings page for the Web site, under Administration, click Go to Site Administration.

Under Management and Statistics, click Manage user alerts.

On the Manage User Alerts page, select a user name in the Display alerts for _ box, and then click Update.

To delete an alert, select the check box next to the alert, and then click Delete Selected Alerts.

See the group setting of the group where you are adding new users?

There must be checked the option of sending emails when user will be added.

I have dll that running when ever user added to groups. I removed email id from there.
