Michael appears to be at Michael Weinberger .
I'm pretty sure his RPM supports IMAP over SSL. For it to work properly with IMP 3, though, you'll need to make some changes to the servers.php template:
mkdir -p /etc/e-smith/templates-custom/home/httpd/html/horde/imp/config/servers.php
cp /etc/e-smith/templates/home/httpd/html/horde/imp/config/servers.php/40Servers \
/etc/e-smith/templates-custom/home/httpd/html/horde/imp/config/servers.php/
pico /etc/e-smith/templates-custom/home/httpd/html/horde/imp/config/servers.php/40Servers
Change:
'folders' => 'Mail/',
'namespace' => '',
to:
'folders' => '',
'namespace' => 'INBOX.',
