Honestly, this is the only place I see it - I have enough mailing lists and rules as it is, so I appreciate it here, but I can understand those who don't want to see it. I definitely think some kind of header flag or subject pattern to match would be a great 'meet in the middle' solution overall. -----Original Message----- From: Mel Beckman via NANOG <nanog@lists.nanog.org> Sent: Friday, November 28, 2025 4:13 PM To: nanog@lists.nanog.org Cc: nanog@lists.nanog.org; Mel Beckman <mel@beckman.org> Subject: Re: NANOG Featured on "Packet Pushers" Podcast Network! š¦ Happy Thanksgiving! + More But the news@nanog.org header only appears because it is a CC. This may not be consistent and itās certainly not obvious or convenient to filter on. Perhaps Nanog will meet us halfway, and put right in the subject line āNANOG promotional emailā or something like that. Seriously. Or just let people subscribe toe news@nanog.org if they want those things. -mel via cell

Ah, the power of `procmail`:
PROCDIR=$HOME/.config/procmail
:0 * ^List-Id: .*\<([a-z0-9-]+\.)?arin\.net\> { SWITCHRC=$PROCDIR/arin.list }
:0 * ^List-Id: (North American Network Operators Group|.*\<(.+\.)?nanog\.org\>) { SWITCHRC=$PROCDIR/nang.list }
# vim: set filetype=procmail:
Not many know about `INCLUDERC` and `SWITCHRC` directives in `procmail`. But hopefully you got the idea. And it will help you break-down `procmail` config into multiple ones and group filters based on categories.
Didn't knew about Google Apps Script. Thanks Tom. Gives me something to look into.
And happy holidays everyone.

Thatās great news, Tom! Perhaps youāll share your filter for dropping NANOG promotional emails? And no fair using ChatGPT :)
In my Google Apps Script that I use for header based filtering, I would just do this:
... // NANOG Newsletters var from_h = message.getHeader("From"); var reply-to_h = message.getHeader("Reply-To"); if ( (from_h.includes('nanog-announce@lists.nanog.org') && reply-to_h.includes('news@nanog.org')) {
message.getThread().addLabel(GmailApp.getUserLabelByName("NANOG-Promo")); message.getThread().moveToArchive(); } ...
In a real mail client this is easier, but same idea.
