Hi,
I’m migrating a domain to Mailcow from an “old-style” Courier server, and I selected some users for the test period.
So I enabled a temporary domain to Mailcow and I moved test users from real mail accounts to alias to a temporary mail address on the temporary domain on Mailcow.
I enabled the option “disable sender check for domain *” on “Allow to send as” configuration in the mailbox setup but some received messages are still rejected as spam from Rspamd because of the DKIM check, expecially for messages sent from Google Gmail:

How I can solve this problem?
How I can disable DKIM and DMARC checks during the switchover until all users will be migrated and I will migrate the real domain (and its MX record) to the new Mailcow server?
Thank you very much!
Bye!
