Hi Community!

I need Help to finde the source of my problem.

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,

This has nothing to do with Plesk.

You have simply configured your website incorrectly.

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.
