Scanning for spam AFTER mail is in inbox

Hi all, I'm migrating a huge amount of mail from one server to another. What I'm seeing is that a lot of the users for this account have tens of thousands of messages in their mailboxes that are extremely spammy. It would be wonderful if I could run any sort of spam filtering utility to sort spam into the junk mail filter so it can be easily deleted, rather than migrating years and years of junk mail to the new server. Has anyone done this before, or have you any ideas about how (if) this can be done? Many thanks! Take care, Beth

  Does anyone have a answer for this?

  How does one run spam filter manually on an inbox or a folder?

  i.e re-scan after filter rules have been adjusted.

  Thanks
  Nathan

  Nathan - you can use SpamAssassin's sa-learn utility to handle this work.  Details on running that can be found here: https://support.cpanel.net/hc/en-us/articles/360053149353-How-can-I-teach-SpamAssassin-to-identify-more-Spam-email

  Thanks Rex.

  I thought this might be exposed in the GUI somewhere so users can manually re-scan their inbox after adjusting the scoring.

  I found that if Spam Box was disabled during a migration to cPanel or if scoring options were not strict enough then the inbox will still potentially contain malicious emails that should go to Junk.

  I'll submit a feature request and see if it garners any attention.

  Cheers
  Nathan

  Sounds good - I'm not sure if we'll have the features meeting the next two weeks with everything that has been going on lately, but I'll get to it and send you a follow-up email!
