The problem occurs when wwsympa try to sendto listmaster a creation request
message. That's a Perl trouble coming from SUID bit. Teh solution is to run
perl with the -U option (add it in wwsympa first line) to allow perl
to unsafe operations.

That's interesting. There is at leat 3 problems
-1- SUID root which is a real security question. 
-2- Aliases files location. /etc/aliases is not the only possible
path for alias file. From my opinion, Sympa configuration about sendmail
should not contain anything else sendmail path.
-3- Remove aliases is important also

Some has install a specific sendmail or postfix configuration in order
to pipe all incomming messages to the queue program without aliases. Nice
solution that require a dedicated domain for lists and some patch in sympa
itself because sympa must answer "user unknown" in some case.

"Developing guidelines" : no official guidelines. Please submit your script
as is. We will check it and send you suggestion about it's integration in 
sympa.

Your are welcome ! V3.0 templates are now quite stable.
