[Mailman-Users] Spam detection issue

[Re@lබණ්ඩා™]

Hi All,

I've detected something doubtful situation in mailman because it has
released an email with spam flagged. I'm attaching my received email's
header which is flagged spam yet released by the mailman. But I've checked
this scenario many times later but mailman was rejected them all as it
should be. Can someone explain what would be the reason here? Or is it may
be a bug?
