I have tried several times to change the email address for my Atlassian account (my.atlassian.com). The current email address is a Gmail account and receives the notification message that an email address change has been requested. The confirmation message never arrives on the new email address.

Hey, welcome to the Community!
Our mail system logged a soft delivery error when attempting to deliver the verification email to your new address. I've emailed the error to you at the address you're trying to switch to. If you're able to find an email from me at your new address, it seems like there may have just been a temporary problem between our mail delivery system and your domain's mail server.
To resend the verification email, you can try logging in again at https://id.atlassian.com with the new email address. Currently there aren't any blocks in our system to prevent further email delivery to your email address.
If you haven't received an email from me directly, it's likely there's some continued misconfiguration with your mail server. Trying to send the verification email again while mail server is misconfigured could put your email address in our bounce list. After any misconfigurations are taken care of, I can check our mail system again to make sure your email address isn't on a bounce list.
