Thank you.

debug_log "envelope to `${1}'";
debug_log "envelope to detail `${detail}'"; <= is this a default
                                                variable?

I get
===
sieve: info: started log at Sep 15 21:07:07.
lists.sieve: line 15: info: DEBUG: envelope to `al-pdnsusers at none.at'.
lists.sieve: line 16: info: DEBUG: envelope to detail `'.
info: msgid=<20110915190707.256ED9FECC31 at external.none.at>: stored mail
into mailbox 'Lists.pdnsusers'.

Is there a possibility to print the :detail from the subaddress module?
Maybe like

Pseudocode:
===
set "detail" :detail if :detail not empty
===

Is there a possibility to dump all variables?
Are there any default variables in variables module?

What does I make wrong that I haven't the :detail from the subaddress?!
