We run a RHEl6/CentOS6 shop. RH ships RHEL6 with Mailman-2.1.12, backporting security fixes as necessary but without incrementing the version number. This is what is available from CentOS in consequence. EPEL does not appear to have a more recent version available either. Bottom line is that I do not have access to an approved packaged version of a more recent Mailman so that i cannot do a you suggest. Presently I am attempting to build a 2.1.18 packaged version for our internal deployment. Unhappily, RH puts things for Mailman-2.1.12 in many different places from those given in the source. Thus getting the new version built successfully and then installing correctly is proving a tad tedious. Thanks for the suggestion though. If I ever get the replacement built correctly or source a 2.1.18 package elsewhere then I will use your suggestion. Regards, -- *** E-Mail is NOT a SECURE channel *** James B.
