CVE-2019-13612: Altn MDaemon Email Server

High severity, CVSS 7.5. EPSS: 1.3% chance of exploitation in the next 30 days.

MDaemon Email Server 19 through 20.0.1 skips SpamAssassin checks by default for e-mail messages larger than 2 MB (and limits checks to 10 MB even with special configuration), which is arguably inconsistent with currently popular message sizes. This might interfere with risk management for malicious e-mail, if a customer deploys a server with sufficient resources to scan large messages.

Affected products
