For those who might want an RPM of imapsync for their RHEL4 installs (this will likely work just fine on RHEL3 or the accompanying CentOS releases, and probably on Fedora as well; I've only used it on CentOS4 right now), here's a spec for it. You'll need to grab the latest release from the
imapsync web page (and you'll probably need a couple of Perl RPMs from the
DAG repository; specifically, perl-Mail-IMAPClient, perl-Net-SSLeay, and perl-TermReadKey) and perl-IO-Socket-SSL from Red Hat/CentOS. Enjoy.
