Package: minimalist
Version: 2.5.3-4
Severity: normal
Tags: patch
Hi
I occasionally see minimalist sending "Bad syntax or unknown instruction" mails
to MAILER-DAEMON addresses. They are triggered by spam with such an address in
the Reply-to: header.
The minimalist code checks for MAILER-DAEMON in From:, Sender: and X-Sender:
headers, but misses Reply-to:.
The attached patch fixes this.
Best regards
Tomaz
