Back to this:

this is the remote-client folder right? in

lucee-server.xml

there's

<remote-clients directory="{lucee-config}remote-client/"/>

I'm curious as to how the mail spool dir ended up with the name

remote-client

. Instead of - maybe -

mail-spool

or something a bit more on-point? However within that dir there is a subdir

open

(eg:

/usr/local/lib/serverHome/WEB-INF/lucee-web/remote-client/open

) and it seems that's the actual spool dir: I see email objects being created in there, and undelivered emails persist there until I run the task in admin. Am I reading that right? NB: that I need to ask questions like this is perhaps indicative that better dir naming might be helpful here. Contrast with CF:

cfusion/Mail/Spool

and

cfusion/Mail/Undelivr

. Easy to tell what's what there.

not an actual answer to your question just my speculation. I think it is named that way because it is written using an abstraction that could be used for other queue / spool type functionality, I think some other stuff uses the abstraction besides just cfmail

Hrm.

looks like cfthread may use it: https://github.com/lucee/Lucee/blob/e97119ecd996104863991ccef193ac97ebf8c3ab/core/src/main/java/lucee/runtime/tag/ThreadTag.java#L314

Even if something else is using it "remote-client" makes as much sense as "bonobo-fingers" does, as a dir name.
