Soft Bounce Undeliverable Email Notification

I received a number of "soft bounce" notifications yesterday and this morning - both to a guest email address and my own email address. The notifications were on emails tied to different reservations. I've checked with the guest and they have received everything that I emailed them. Any ideas what is causing this?

A "soft bounce" means that the email was temporarily unable to reach the email address, but it will automatically try again several times over the next day or two. This can happen for many different reasons -- maybe the email server is down for maintenance, maybe the account is out of space, etc.

That's different than a "hard bounce" which means the email has been dropped and will not be retried. That happens for permanent reasons like incorrect email address, spam blocks, etc.

In your case, the bounces were all to your email address, not the guest's email address -- the copies you get and notification emails were soft bounce, not the ones to the guest. The guest's emails show opened.

Do you see the emails coming to your email address now? It was likely an intermittent issue and has been resolved by your email provider already.

FYI, these are still bouncing to you, but if they're bouncing that means no emails are getting through from us, so you probably didn't get the notification on the forum post.

If you check back, circle it up and let us know what was going on with the account... maybe out of disk space?

Chris, I am so puzzled as to why this is happening. I thought maybe AT&T (Yahoo) just had a temporary hiccup, but then it happened again early this morning with a notification of a security deposit being reserved for ORB1562769. I received the notification email at 3:07 am, and then the soft bounce email from OR at 3:08 am.

I have only used 0.47% of my 1 T storage with AT&T, so there's no way that I'm out of space. I hope you have an idea for me. I have started searching this issue, but so far haven't found any answers. Thanks!

Are the emails still getting through to your att.net account fine, just showing a bounce and maybe a couple of minutes delayed?

Yes, I am receiving emails fine and showing a bounce a minute or so after.

Looked into this further and it's actually a second level bounce -- looks like there is a forward to forwardfromatt@gmail.com and that is what's bouncing, not the initial send to your @att.net account.

Can you disable the forward from your @att.net account? That should solve the problem.

Yes, I have disabled that forward now. Thank you so much for finding the solution!!
