The email DNS on your domain was a little outdated. I've manually updated this on my end. It may take up to 24 hours for propagation, but should resolve this issue.

Hi elyzabethv,

I was having a similar issue with one of my employees tried sending me an email and they received this as a response:

The message they are receiving is:


You're sending this from a different address or alias using the 'Send mail as' feature.  The settings for your 'Send mail as' account are misconfigured or out of date.  Check those settings and try resending.

The response from the remote server was:

535 Incorrect authentication data

Can you help?  We have updated our DNS a few weeks ago.  Anything else I can do?

What is the email box you are getting this response from, and do you know if anyone else is getting this same type of message when emailing you?
