Updated atmailopen to v. 1.04 (released Jan 21st 2009).
The last official release was in fact 1.05 (released March 26th 2012), however, it is not available for download from atmailopen.org anymore, and I couldn't find the archive anywhere else.
I downloaded the 1.04 archive from one of the FreeBSD ports mirrors (most likely this one: ftp://ftp.free.fr/.mirrors1/ftp.freebsd.org/ports/distfiles/atmailopen.tgz).
Merge branch 'atmailopen-1.04'
