I have started to get
Delivery Status Notification (Failure) messages in response to emails sent from my Google Apps domain account (at offby1.net):
Delivery to the following recipient failed permanently: **firstname.lastname@example.org Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 535 SMTP AUTH failed with the remote server.

I'm sending messages to various ISPs; not just gmail. The only thing that might be an issue is that the from: address is my old gmail account address, which forwards to my apps account at offby1.net.
What is causing this? How can I stop it? This has been going on for about four days now, and it's happened once before, but I never was able to ascertain why.
Because it probably bears on this, I am not using an SMTP server of my own, nor in fact am I sending this using an email client on my desktop. I'm using the Google Apps webmail client to send this, so if there's an SMTP server configuration at issue, it's nothing I've got any control over -- that I know of.
