How can it be, that I get this Log Entrys, after I deactivate the Website and the Mailservice from this domain?

W2Serv-R2D2-2019 ... is my Plesk Host (Plesk ObsidianVersion 18.0.21 Update #3). An SMTP needs Login to send Mails. So how could it be, that my Server says it can not send mail from [email protected] to localhost.com, after I change Password.

Please Help, I have no Idea! Thanks!

Kind regards,
Wolfram Sulzberger
 
This has nothing to do with Plesk.

You have simply configured your website incorrectly.

[email protected]
[email protected]

Your website is trying to connect to localhost.com to send the emails.

You have mentioned that you are receiving returned emails every 5 mins. This could be Spambot trying to send you spam emails via your contact form but they fail due to the above issue.
