Migrate from Namecheap email to mailbox.org with own domain
Sorry for my bad english :(
First i add my email account (from namecheap service) from the left email panel. Move all the mail to the mailbox.org folders and now i got all my mail to the new mailbox account.
next i go to alias setup and add my email@example.com to add external address and have tipical dns error with the domain and key.
Now i create a new TXT record (info from https://userforum-en.mailbox.org/knowledge-base/article/e-mail-addresses-of-your-own-domain) to namecheap domain panels (https://www.namecheap.com/support/knowledgebase/article.aspx/317/2237/how-do-i-add-txtspfdkimdmarc-records-for-my-domain) add my information for host: 2fdg4434g4XXX...mydomain.net and value: 12df44tg54g3XXXXX...
After 2 days i continue to have the Error: Validation of external domain failed
How i can migrate?
