    Yes, I'm still running my ancient mail server. As it is still on ESM, it is maintained and secure.
    After the latest update (3.2.4) and making larger change to the email filters, I noticed all mail got delivered to the Junk folder.
    I found out that this is because of the following part of commit
    This breaks my setup as the X-Spam-Status header looks like this:
    The "YES" in BAYES is matching the case sensitive check done by sieve:
    The fix is to make this test case sensitive:
    Please review this fix and make it part of the next release. I manually altered the template file and the affected sieve file.
    (note: one can edit the sieve file and just remove the svbin file, the latter is automatically recreated.

    This concludes a long evening of hacking :)

    (who learned a lot about debugging Sieve files now :))

    Thanks for the report. Another option would be a positional match, eg.
    if header :matches ["X-Spam", "X-Spam-Flag", "X-Spam-Status"] "Yes*" {
    if anyof (header :is ["X-Spam", "X-Spam-Flag"] "YES", header :matches "X-Spam-Status" "Yes, *") {
