Please add "amd64" to the KEYWORDS for net-mail/offlineimap-4.0.0. I have tested and found it to work. Additionally, you should probably unmask *all* Linux architectures. OfflineIMAP is written in pure Python and will work on any machine that Python works on. Note: I am the upstream author of OfflineIMAP and have verified several of these platforms on Debian.
