Bounces from Yahoo

[Kevin Miller]

Yes, I know.  Hence the "The cause is duplicate subject headers." in my post.  The question is, how do I fix it?  Yahoo apparently does something that causes MailScanner to do that.  Maybe some mutant grey-list process?  I dunno.  I can't duplicate it at will - if users wait a while and resend the message will go through, I think because it hits a different ingress server.

Andrew Lissa writes that it's fixed over there:  "It is an issue within MailScanner not baruwa, will try get some time to push it into MailScanner proper on Github, since the enterprise MailScanner is a fork it requires some time to do so.  Will do that when I get some space time, hands full at the moment."

Be nice to see the patches in MailScanner proper.

There's a similar thread over in the Baruwa neighborhood, but apparently it's a MailScanner bug.  They mention a fix over there but I don't know that it's made it to github for MailScanner yet.

Anyone else having this issue?  Any patch files out for it?
