I want to be able to send email from anywhere using my qmail/vpopmail/courier-imap server. It seems there are patches for qmail, roaming-users config for vpopmail, and other patches for courier-imap. Currently vchkpw is my authentication method for pop3 and imap.
What is the best way to go? Do I need each to be patched? I can't find a how-to that works. If this is a common configuration need, why is it not easy to turn on?
