Because cPanel provides Mailman and Python as part of their distribution. When they first upgraded to a Mailman that included DMARC mitigations based on DNS policy lookups, they included dnspython in their Python package. They have apparently shipped a recent update that upgraded their Python 2.6 package with dnspython to Python 2.7 without it, thus breaking their Mailman package. ... > As I recall, as well, there were, at one point, not one but at least > two DNS resolution modules available for python - dnspython, PyDNS, and > now perhaps python-dns, which are similar but differ with regard to > such trivia as the case of the module name in import directives, but > which will surely cause exceptions if the calling conventions aren't > strictly followed. You are correct. Mailman as distributed by us requires dnspython and won't work with PyDNS. python-dns is the RedHat/Centos name for PyDNS. > This all underscores the problems of relying on other people's > organization, and the resulting dependency on other people's confusion > that comes from blind reliance on über-packages (especially proprietary > über-packages) such as cPanel which obfuscate and complicate solutions > to simple problems.

Agreed, but such packaged solutions have a place. I don't know what Scott's situation is or his reasons for using cPanel, but I know Brian operates a shared hosting service, and I know from his participation on this list that he is conscientious in providing good service to his customers, and without something like cPanel, his business might not be viable. From my point of view, I think everyone should install Mailman from my source. Then I wouldn't ever have to deal with issues caused by downstream packagers, but that's unrealistic in the real world. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
