Spam filtering

[dransome]

Old KB URL: https://kb.layershift.com/installing-plesk-email-antivirus and https://kb.layershift.com/add-spamassassin-to-plesk
New KB location: Cloud VPS > Email > Spam filtering

Goal

Describe the available spam (and virus) filtering options.

Content summary

Present the various included options to reduce incoming spam (what they are + how to configure):

• server-wide settings including DKIM, SPF, DMARC verification, greylisting
• DNS block lists
• SpamAssassin

And also the optional paid options to address anti-spam and anti-virus:

• Plesk Email Security Pro (covers anti-spam and anti-virus)
• Kaspersky AV (anti-virus only)

Notes

The pages on old KB focus on how to order the extensions, but otherwise miss the overall issue and do not adequately cover the actual topic (options available to reduce inbound spam!). Although this article is marked for import from old KB it really needs new content.
