Suddenly getting error msgs: "Mail delivery failed: Returning message to sender" immediately after receiving msg
I receive an email and immediately afterward get the error msg that an email that I tried to send was rejected, but I did not try to send an email.

Do you have an auto reponse set up ? Please note an auto response might be set up in your webmail account accessed via a browser, so please check that as well.
In Thunderbird Check out any auto sending of Return Receipts. Menu app icon > Options > Advanced > General Click on 'Return Receipts'
When I receive a request for a return receipt: Is this set up to allow return receipts automatically or to 'Ask'?
Do you have a 'Message Filter' which may be auto replying when emails are received ? Perhaps you set up an out of office type of response and forgot to stop it. This could be in Thunderbird, but it could also be set up in webmail.
