full imap source is included on php source for imap support,
all what is really needed is c-client.a and the include
files for c-client.  Both could be on a -devel package from
imap (bug 5098)

when this imap-devel package is used, the imap source could
be taked out, and will be replaced with the following

from the php-3.0.12-4's spec (the lines that had changed are
 listed below)

#Source2: imap-4.5.tar.Z
#Patch1:    imap-4.4-vfs.patch
#Patch2:    imap-4.5-linux.patch
#Patch3:    imap-4.5-redhat.patch
