Bad Mail config with mixed case domain name

DavidePrincipi commented 3 months ago

If a domain is created with mixed case chars, the configuration of Postfix is wrong:

Steps to reproduce

Create OpenLDAP domain dp.nethserver.net
Install Mail with domain dp.NethServer.net
Send a message to first.user@dp.NethServer.net

Expected result

Message is delivered

Actual result

< 554 5.7.1 <first.user@dp.NethServer.net>: Recipient address rejected: access denied
* RCPT failed: 554

Expanded configuration excerpt

[mail1@rl1 state]$ podman exec -ti postfix postconf -n | grep NethServer
smtpd_recipient_restrictions = reject_non_fqdn_recipient, check_recipient_access inline:{ dp.NethServer.net=reject_unverified_recipient dp.nethserver.net=reject_unverified_recipient go.nethserver.net=reject_unverified_recipient },
virtual_alias_domains = go.nethserver.net,dp.NethServer.net
virtual_alias_maps = sqlite:$meta_directory/aliases.cf, sqlite:$meta_directory/wildcards.cf, , ldap:$meta_directory/ldest.cf, sqlite:$meta_directory/userforwards.cf, inline:{{@dp.NethServer.net=@dp.nethserver.net}},

Test case

Install Mail 1.3.6-dev.2

Check the bug is not reproducible
Create an address like DuDE@example.com and check the message is delivered
