You are trying to install gmime20.i386 0:2.2.26-1.el5.rf, which will remove gmime-2.2.10-5.el5.centos. However, your currently installed gmime-sharp-2.2.10-5.el5.centos requires gmime-2.2.10-5.el5.centos. You need to either remove gmime-sharp-2.2.10-5.el5.centos or find an updated version that will work with gmime20.i386 0:2.2.26-1.el5.rf. -- William Hooper
