The line above is redundant if you haven't first changed
DEFAULT_URL_HOST or DEFAULT_EMAIL_HOST.

This may or may not be correct depending on your Postfix configuration.
If 'something.domain.com' is in virtual_alias_domains in main.cf, then
the above is correct, but if only 'something2.domain.com' is in
virtual_alias_domains (something.domain.com is mydomain), then you want

POSTFIX_STYLE_VIRTUAL_DOMAINS = ['something2.domain.com']

I'm not sure what the exact cause is, but the problem is that
/usr/sbin/postalias when run as user=(apache or whatever your web
server runs as) and group=mailman doesn't have sufficient access to
read /etc/mailman/aliases and/or write/create /etc/mailman/aliases.db.

This may be a SeLinux issue. It may be a simple permissions issue. The
location of aliases and virtual-mailman in /etc/mailman is a RedHat
specific FHS modification, and I'm not sure about the permissions in
this case, but I think /etc/mailman should be group:mailman and
permissions rwxrwsr-w, and the aliases and virtual-mailman files
should be also group:mailman and permissions rw-rw-r--.

If the permissions are as I note (in particular /etc/mailman/ is
SETGID, group writable and group:mailman, and the files are group
writable, group:mailman and world readable), and you still have this
problem, then I think it must be a SeLinux issue.
