Peope keep getting a message "Cannot replay. Shut down for the day" from our email. Why?

more options

After we send an email to someone, they get it and they send a reply. Then they get an email from us with the Subject: "Cannot Replay". The text reads: "Shut down for the day." Then we get an email from the person wondering if we got their email (which we did) and wonder why they got that email from us.

Chosen solution

When people reply, are they sending the message directly to your (company) address, or does it pass through an intermediary (for example, marketing service that tracks response to email campaigns)?

How many computers have access to your inbound mailbox? If you share it with other users, try having everyone log out to see whether the message could be sent by the server rather than by any of your individual mail clients.

Can you replicate the problem by sending a message from a personal email account? That would let you inspect the message headers and see whether there is an IP address identifying a particular machine as the source.

Well, it's not a message from the Thunderbird program itself. More likely a server. Or have you ever set up an autoreply using a filter and template?

Does it really say "replay"? Not "reply"?

Shut Down For The Day.

Above is the message people are getting from us. We have never set up any auto reply on our email.
