Yeah, there's inline-forwards and forward-as-attachment, and I use those both heavily for doing things like spam analyis (and have had to show my coworkers where those options are since yeah, there's not an obvious UI icon for them). (So, that's at least three different definitions of "Forwarding") I imagine it's only a trivial amount of perl to basically get procmail or whatever to do either of these, if I needed it to, but it's absolutely not a wrapper that's conveniently built into sendmail that I can drop into a virtusertable or a .forward. There's no mode-switch there to change the behavior of "[email protected] <mailto:[email protected]>" for the users. Or the rules that are set up in our corporate mail server (which I think use Sieve under the hood). This moves sendmail/postfix/etc from the point of being "MTA" to "automated/scripted MUA", but it's only one or two users who do this, and, honestly, it lets me keep up with the joneses. Behavior like this affects users at the dayjob, even those who want to set up a vacation forward to their gmail for some subset of messages. -Dan PS: There's a youtuber I follow who reacts to things by starting, asking frustratedly "What is it now...?" I must admit, I've heard that phrase echoing in my head lately.
