Re: [Mailman-Developers] Support for X-No-Archive

http://www.mail-archive.com/faq.html specifies "X-No-Archive: yes"

It's been a long time, but I vaguely remember lowercase 'yes' being canonical which is why we specify it that way in the FAQ. In practice mail-archive.com treats the header as case insensitive.

Here's some data on common practices, taken from a recent week of mail-archive.com's inbound mail.

$ zgrep -i "^x\-no\-archive:" *.mbox.gz | cut -f3 -d":" | sort | uniq -c

 72  no
183  No

6407 yes 108 Yes 47 YES
