Hello, first of all I’m really impressed about mailcow and would like to say thank you for doing such a great work!
I’m in a migrating process from an old mail server to a new mailcow instance and have a question about moving domains with enabled MTA-STS policy.
I know there is a recommendation to set those records’ mode to „none” for about 2 weeks when completely disabling MTA-STS policy but how is it when moving? Do I have to pay attention to something else except setting a new ID? Are there any different procedures for primary domain (mail server) and for additional domains (which use primary’s domain MX)?
Thanks in advance!
