### Description of my problem
Hello all,
I would like to add a mail alias with a wildcard to an account, so that it receives all mail in the form “[mailboxUNIQUECODE@example.com](mailto:mailboxUNIQUECODE@example.com)”. I tried adding a mail alias in the form “mailbox\*@example.com” but I get the error “Error: Invalid argument ‘add\_mailalias’: Must be a valid email address (e.g. [someone@domain.org](mailto:someone@domain.org))”
Is there a way to setup such a system? I would also be able to work with a catch-all mailbox, which receives all the messages sent to the server.
Thanks to everyone!

I, too, would like to know whether wildcard or catch-all email addressing is doable. Thank you!

I tried to create an alias `*@demo.yunohost.org` on the demo site, but it’s rejected
Would be great if there’s official support of wildcard email alias, thanks!

Hello,
Yes it will be a good feature for me too. 😀
Is there another way to do this ?
Thanks

For the moment, only the + selector support is available.
SO email+XXXXX@domain.tld
BUT you can do it “by hand” and with cli, you need to change /etc/postfix/main.cf with:
```auto
virtual_alias_maps = hash:/var/lib/mailman/data/virtual-mailman,ldap:/etc/postfix/ldap-aliases.cf,regexp:/etc/postfix/aliases-regexp
```
Create a file /etc/postfix/aliases-regexp like this one:
```auto
/mailbox.*@example\.com/ mailbox@example.com
```
Use postmap on it
```auto
postmap /etc/postfix/aliases-regexp
```
Define in yunohost admin an alias [mailbox@example.com](mailto:mailbox@example.com) on a user.
Restart postfix
```auto
systemctl restart postfix
```

This worked! ([Mail on main domain, yunohost on subdomain - #3 by samuel-ynh](https://forum.yunohost.org/t/mail-on-main-domain-yunohost-on-subdomain/21935/3))
But unfortunately only for receiving mails, if I try to send a mail from a wildcard alias I get:
`Sender address rejected: not owned by user`
Do you have an idea on how to send mails from wildcard aliases?
Thanks in advance!

J’ai eu quelques erreurs de correspondances des regex. J’ai compris qu’il faut bien borner la règle.
Exemple :
`/mailbox.*@example\.com/ mailbox@example.com`
va correspondre à : `mailboxdetoto@example.com`
mais aussi à : `toto.mailbox1@example.com`
Si on ne veut pas alors il faut plutôt écrire `/^mailbox.*@example\.com/ mailbox@example.com`

Hello, to make it working I commented the line : `reject_sender_login_mismatch,` in the `/etc/postfix/main.cf`
```auto
# Requirements for the sender address
smtpd_sender_restrictions =
# reject_sender_login_mismatch,
```
This maybe a security choice.

Apriori this means that anybody can send an email using anybody’s identity so yeah … “Couldn’t figure out what’s wrong with the keys, so we removed the lock and now anybody can enter the house, problem solved” 😅
