After Restore Dump Spam out of order

[AGRV]

Hello,

after a server crash I have to reinstall Plesk. I restore my Plesk-dump but now the spam service for all restored e-mail accounts is disabled. Now I tried to enable the SPAM-service on my account. No way :-(. The only way I found, was to delete the Account and create it new. But I will not delete the accounts because all mails in the IMAP Folder where deleted.

How can I solve this problem?

Thanks and greetings from Germany
