Hello,

Mail failure - malformed recipient address
A message that you sent contained one or more recipient addresses that were incorrectly constructed:
….


Its every time the same email. How to stop this one and only email attempt, sending out tons of emails as "Mail failure - malformed recipient address" ??
Where can i delete this email queued (?)

i got after hundreds of emails this email:


---------

This message was created automatically by mail delivery software. A message that you sent has not yet been delivered to one or more of its recipients after more than 24 hours on the queue on server.xxxxx.de.

The message identifier is: 1k28lG-0006Y9-9k

The subject of the message is: =?utf-8?Q?Bist=20du=20mit=20deiner=20Bestellung=20bei=xxxxx=3F?=

The date of the message is: Sun, 02 Aug 2020 07:50:25 +0000



The address to which the message has not yet been delivered is:

[email protected]

No action is required on your part. Delivery attempts will continue for some time, and this warning may be repeated at intervals if the message remains undelivered. Eventually the mail delivery software will give up, and when that happens, the message will be returned to you.
--------
The problem might have been the "dot" in the email between 82 and tt?

But, how to stop this now? its still ongoing :-(

Are these messages you're sending? This looks like a script is sending mail from your server. What is the output of the following:


Code:
