According to httpoxy.org, HTTPS is not affected by HTTP_PROXY statements.
"And, of course, another defense-in-depth strategy that works is to
use HTTPS for internal requests, not just for securing your site’s
connections to the outside world. Those aren’t affected by HTTP_PROXY."
Of course, that's if you are using a very complicated split-mailman
setup (web on one system, other parts on other hosts), If not, then
what in your httpd.conf is would be proxying? And if nothing is
proxying, then why haven't you already disabled proxy statements? Are
you running anything else on the mailman server, PHP, etc?
