Mail creation from Plesk Panel GUI hangs. In Task Manager you can see a lot of 'spammng.exe' processes. One of the possible causes is that spam training process fails because a mailbox (or a folder) name contains ' (apostrophe) symbol.

Please follow the blow steps in order to make sure that the above is your case:

  1. Create email, mailbox name contains the ' (apostrophe) symbol
  2. Send few email and move some of them to the 'Te'st' folder in webmail.
  3. Run DailyMaintainance script and it hangs.


Plesk Panel issue with id #PPPM-1119. The mailbox name should not contain the ' (apostrophe) symbol.

This issue was fixed in Plesk 12 MU#7.


Apply the latest Plesk update or upgrade your Plesk to version 12, according to Installation upgrade and migration-guide: Installation upgrade and migration-guide

If by some reason you cannot apply the latest Plesk microupdate, as a workaround remove ' (apostrophe) symbol in the mailbox and mail folders names.


  1. Find mailbox folders with apostrophe symbol in name.

    dir /s /b \full\path\to\mailboxes\*'*.* > C:\list.txt
  2. Remove apostrophe symbol from folder name listed in C:\list.txt

  3. Kill all hanged spammng.exe processes

    taskkill /IM spammng.exe
