Yep, been there read that.....
and that produces X-Spam-Myserver-Status etc... which was easy.
But you originally specified X-Server1-Spam-Status which seems a little harder.
I'm suspecting a wordo, like a typo, but bigger :-)
Actually, it's limit in SA's header generation that I forgot about. I forgot that it forces X-Spam as a prefix.
I use MailScanner and that limit isn't present in MailScanner. I can modify my headers to be literally anything I like, hence I do:
X-EVI-MailScanner-SpamCheck:
But I could tell it to do:
Y-Someheader-Garbage:
and Mailscanner would do it (although not having it begin with X- would be a bad idea, I could do it)
