spaming from my domain
We have required "authentication" when sending emails, and make sure no one in my server sending spam. But today, I received many returned emails, for "xysmdcb@mydomain.com", "8cvh48f@mydomain.com", "d3jd83sjfg@mydomain.com"... you can see the address before @mydomain.com is randomly.
How can I prevent this kind of spamming?Traditional music traveling

From the sounds of what you've described... you can't.
You can't really do anything to prevent someone from sending out mail forged to use an address from your domain.
It should be fairly easily identifyable from the headers in the bounce messages that the origin of the emails are not from your server.
One thing you can do which will help recipients more easily flag those messages as spam is to setup SPF records for your domain.

No, these messages are not from my server. It seems an automated thing from somewhere else... My domain has SPF record already
