Hi,

I managed to receive mail on my own domain with wildcards/regular expressions. For example `user@example.com` receives all the mails in the form of `*user@example.com`.

But unfortunately I’m not able to send mails from this account with the corresponding sender.

I would love to be able to send mails as `*@example.com`.

I’m not familiar enough to know the right postfix options.

Thank you for your help!  
Samuel

Domain Yunohost runs under yunohost.example.com, the DNS is set up according to the generated DNS config by Yunohost The domain example.com was added as well, but only the DNS entries corresponding to mail were added.

Hi

Not sure to all understand, but if you want to send a email to all users of your yunohost server, you can see this thread

Sorry, then I was unclear in my first post.

Every user has its own mail-space where she receives mails to the addresses in the space `*username@example.com`.

But unfortunately they can only send mails from `username@example.com` and not from all mail-addresses in the form of `*username@example.com`.

Right now I _fixed_ it with the commenting out `reject_sender_login_mismatch` in the postfix `main.cf`.  
But that is not the perfect way to handle it, I guess.
