Searching Webmaster World only seems to bring up old posts on CPanel vs H-Sphere.
I have an annoying problem with a mailing list under H-Sphere which can't be resolved easily at the user level. I've tried in vain to locate an appropriate forum for end users as opposed to forums for hosting companies.
Essentially I want to ban HTML replies, ban attachments and have reply to: as the list.
All of these were [from memory] available under CPanel which used Mailman vs H-Sphere's EZMLM.
Unfortunately any changes made by my host provider would have a global change and unfairly affect everyone.
