Mailman and byteslog

[slimak]

I have two problems:

1. Mailman:
When I enter mailman (cPanel) from user domain (e. g. http://namedal.pl/mailman/listinfo/wwnig_namedal.pl), then I have an error "Group mismatch error". When I enter by hostname/IP (e. g. http://host2.xon.pl/mailman/listinfo/wwnig_namedal.pl), then every thing is ok. I want to setup mailman accesible from users domains. Force a group nobody for all CGI scripts isn't a good idea. Is there possible to force gid only for specific catalog (e. g. /usr/local/cpanel/3dparty/mailman/cgi-bin) or to setup invisible redirect from http://user_domain/mailman/* to http://main_domain/mailman/*?

2. Byteslog (probably it's a bug):
Sometimes cPanel count wrongly bandwidth. For example yesterday it counted for one account more then 100GB. When I checked bandwidth logs in cPanel, I saw that about 100GB have been generated in one hour. That is impossible, because the server have 10Mbps network card. I checked also bandwidth for whole server (iptables) and there wasn't any such transfer. The lsws must do a mistake in byteslog and then cPanel count two much bandwidth. It happened 3 times in last week (on different servers and accounts). Previously (version 2.2.5 and 2.2.6) wasn't doing such mistakes.
