450 4.1.8 invalid/host-not-in-DNS return address not allowed

I am using my setup for years and never had a problem.

Since noon, I am unable to send my emails with the Verizon smtp anymore. All my emails (with different response addresses mostly @gmail.com) are not accepted by Verizon SMTP anymore and rejected.

Please advise, why unprofressional guy working on your systems?

Just a friendly reminder, this is a forum where users help other users. It looks like your issue may require a Verizon representative to review your account details. Please contact our customer service team via live chat or email at: http://www22.verizon.com/content/contactus/

Question is: Have other users a similar issue (since around 1pm today)? I certainly doubt this to affect only my account or my setup!

While a Verizon employee may occasionally post here, this community is meant mainly for peer-to-peer support. If you need to talk to a Verizon representative, you should contact customer service directly.

I have this problem as well, and I did contact Verizon support, to no avail.  They seemed to think that what I'm doing is not supported, but every web page I went to on the subject (or on "premier support") was broken.

Are you using Verizon DNS or some other.  Also check the server name in your mail setup.  Messages means no MX record found.

Also did you switch over to port 465 (for ssl) or 587 (non-ssl) as they have been saying for awhile.  Possibly they shutdown access to the default SMTP port although I think the message is different for that.

Try a test message to yourself.  Might be some other mail exchange record missing such as the one for GMAIL.
