AFAIK.
Okay, I use delivery mode, so it will not work.

I have tested it with HOME and SIZE and both are available in the
included files (do you mean global variables?).
My solution is now:
.mailfilter
cc "|scripts/buildfilterlist"
include "mailfilters/list"
A directory "mailfilters" in the user's home which contain a lot of
preordered rulesets.
scripts/buildfilterlist
#!/bin/bash
ls -1 mailfilters/* | grep "^.*/[0-9]\{2,\}_.*" | sed -e 's/^/include
"/' | sed -e 's/$/"/' > mailfilters/list
chmod 600 mailfilters/list
The .mailfilter calls a Bash script, which builds a current list of
ruleset files, which the .mailfilter includes again.
So I can add/remove rulesets without changing some others on the system.
The solution is not for mailservers with a lot of incoming mails, but
our internal project mailserver gets less than 100 mails per day
automatically generated from a service.
There is space to optimize it, the grep command can be removed if you
store the list on another location and maybe the two sed commands can be
combined.
Best regards
Andre

[courier-users] using .mailfilters
Hi, I try to split my maildrop rules into different files ordered by filename. Now I would like to execute all these files in batch till one rule will match and exit maildrop. The only file, which maildrop executes is .mailfilter in the user's home. But it should execute all files within .mailfilters directory. My first idea was to include the files witin .mailfilter: include "/path/to/my/home/.mailfilters/*" But it doesn't work. What is the correct config?

And if you have two simultaneous deliveries, there is some risk that mailfilters/list will be empty when one of the maildrop processes opens it to "include" it. -- Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.

The .mailfilter calls a Bash script, which builds a current list of
ruleset files, which the .mailfilter includes again.
This is mostly equivalent to:
ls mailfilters/[0-9]* | sed -e 's/^/include "/' | sed -e 's/$/"/' >
mailfilters/list
There is no need to waste time with grep, when this is much simpler.
However, this is not technically correct. Immediately after opening
"mailfilter/list" for writing, the file will be empty. The new contents of
the file get written to it a short time later. The time in question is
minimal, a small fraction of a second, but it is not atomic, and it's
possible that mail being delivered at that time will attempt to read
"mailfilter/list", and read an empty file.
Marginally, it is also possible that if the list of files is very large,
"mailfilter/list" will be partially written, cut off in a middle of a
statement, and maildrop will encounter a parsing error, and abort mail
delivery.
The chances are small, but real.
The way to do it correctly is to write the new contents into a temporary
file, and rename it. Rename is an atomic operation:
set -e
ls mailfilters/[0-9]* | sed -e 's/^/include "/' | sed -e 's/$/"/' >
mailfilters/list.tmp
mv mailfilters/list.tmp mailfilters/list
