this setting has been a requirement of LP since I've been an employee and Although it possibly hadn't been enforced at times, It has always been a requirement since I've been here.
There are many programs that are well worth picking up, which are quite similar to Outlook, the best of which In my own personal opinion being Mozilla Thunderbird 0.5 easy to configure, is very fast, and has most of the functionality of Outlook. Best of all its absolutely free to use.
http://www.mozilla.orgcoincidently, cpanel was upgraded, but I don't believe this to be the overal cause.
If those systems are running, anything prior to windows ME, it would likely be a good time to think about an upgrade on both OS, and Mail programs.
Now, I'm not saying Its a necessity for Lunarpages customers to upgrade their personal systems, by any stretch. Simply put though, Microsoft no longer provides support, updates, or otherwise for products prior to ME.
Essentially though, a number of factors should be considered.
a. Outdated products, that don't support smtp auth.
b. SMTP auth is a requirement for LP, always has been, and is being enforced.
c. the cPanel upgrade, though I don't believe had anything to do with it, may have.
