[SOLVED] After migrating my custom domain to icloud+: Some Questions
I migrated my custom domain to icloud+.
Seems to work but there are three problems/questions:
Where are all my emails? I used IMAP so i thought that all the inboxes (of the 3 accounts) will besynchronized after the "redirection" to icloud+
I imported three e-mails: Does icloud not seperate those three accounts? There is only one folder in Mail (on ipad and iphone)?
How can i configure the icloud-account(s) in thunderbird?
Thanks for help
SOLUTIONS:
To get your old mails in your new icloud-account, you can use the mail-app or thunderbird (i guess outlook too) and draw the mails in the new folders.
I just draw the inboxes to the new icloud-account-folders and the other stuff to local folders.
Good possibility to minimize. Have to see if it works.
Workaround: Create folders and rules in icloud+, so that the mails will be sorted.
You have to create an app-password that works in thunderbird or other 3rd party apps.
You likely only changed DNS records, so old mail is still sitting on the previous mail servers. icloud isn't a 'typical' mail server so migrating old email to it would really just be copying all of those old emails into your single icloud mailbox. what've you done so far will only affect new email being sent to the domains you've imported to icloud.
icloud aliases all of your custom domains to the single icloud mailbox. So no, you won't have separate mailboxes for each 'account', everything will happen within the one mailbox.
configure thunderbird for your icloud account/mailbox only since all of the emails point to that single destination.
For migrating your best bet is probably Thunderbird or Outlook, whatever you prefer. Use that app to export a copy of your mailbox from the old mail servers, then import all of those into your single icloud mailbox using the same application.
I've never migrated mail into an icloud mailbox though so there may be some hiccups there that I'm not aware of.
Prepare to be continually disappointed. I switched my domain over when it was first announced, and although it certainly works, there are definitely some needed features lacking. Other than centralizing how emails are delivered, there isn't much of a benefit to using a custom email domain. Plus, I've yet to find an iOS app (other than Mail) that works with them.
Regarding migration, have you tried simply dragging and dropping the email from the old account onto the new one? I haven't used T-bird for this, but it works in Mail.
I think this is a Thunderbird issue. They are separate in Mail.app. It even allows you to use a catch-all rule if you're the domain owner. Maybe you could set up smart mailboxes (or whatever the Thunderbird equivalent is, I've not used it in probably 15 years)?
For #3, you need to log in to your iCloud account, head to the profile and security options, and make an application password.
Thunderbird will find all the appropriate settings once you provide your main iCloud email, and you just need to use the application password and everything will just work.
Thunderbird doesn't understand aliases by default (apple's mail apps on MacOS and iOS do). You'd need to add the alias under Account Settings -> Manage Identities for each alias (which is any custom email domain accounts you add, assuming you want to send mail as that user). There is only one account: the iCloud login. Everything else is treated as an alias, and doesn't create its own inbox - everything goes into the singular inbox.
As the other posts said, email won't migrate automatically. The easy way to do it, though, is setup your old email and the iCloud email in email and just drag and drop your email from the old email to your new iCloud one.
