Hi @andreas gstrein!
Well, it's weird that the issue occurs so often
I suggest creating a request to the Support Department to take a look at this issue:
Plesk Support | Create a request
yeah nasty!
we will move to qmail
Hello @andreas,
Thank you for the information.
In case deeper investigation is required, consider submitting a request to Plesk Support (to us or to our partner in case the license was purchased from them).
