Alias iCloud emails not being received by recipients.

I have added two aliases to my iCloud email account. I sent several test emails to my Gmail account. When I sent a test message from my alias email address, the email was not received. When I sent a test email from my default iCloud email address, it was received. How can I send an email from my iCloud email, using my alias, and have it received the same as it is using my default iCloud email address?

iCloud aliases are often not delivered to Gmail because Gmail rejects them when the alias isn’t DKIM– or DMARC-aligned with the authenticated domain. Make sure the alias is enabled on iCloud.com, remove and re-add it in Mail, and send a test message using iCloud.com webmail. If alias mail still doesn’t arrive, contact Apple and request that they regenerate DKIM for your alias.
