There is some problem with your aliases and virtual maps. It looks like
you have installed aliases as virtual_alias_maps instead of alias_maps.
Also, the list name in the aliases should be just the name, not the
email address unless you have also installed some virtual hosting patch
that makes the listname have the domain included. See
<http://www.list.org/mailman-install/postfix-integration.html> and if
gdsolutions.com.ve is a Postfix virtual domain, see

That won't change this.

Note that Mailman/Postfix integration as described in the above
referenced manual pages is for virtual alias domains and not virtual
mailbox domains. You can make this work for list domains that are
virtual mailbox domains if necessary. See the FAQ at

If you need further help from this list, we need to see the output of
"postconf -n", the contents of mm_cfg.py, and assuming you have "MTA =
'Postfix'" in mm_cfg.py, the output of "ls -l /usr/local/mailman/data".

Also, we need to know what if any patches you have installed.
