Where was a message telling me that? (In my original post I included the relevant output.) There wasn't anything there which said the install of gmime20 necessitated removing another, different package.
I'll try to explain, but part of it just comes from experience.
---> Package gmime20.i386 0:2.2.26-1.el5.rf set to be updated
This is the package being installed.
--> Finished Dependency Resolution gmime-sharp-2.2.10-5.el5.centos.i386 from installed has depsolving problems --> Missing Dependency: gmime = 2.2.10-5.el5.centos is needed by package gmime-sharp-2.2.10-5.el5.centos.i386 (installed)
The "from installed" means the that package in question (gmime-sharp) is already installed. The assumption I made, since you provided the output saying that gmime of an appropriate version was installed, is that yum is saying the gmime version needed would be removed. Checking the spec file and finding the obsoletes confirms that.
Yum used to give similar messages when you tried to "yum erase" a package that would break dependencies. Newer versions of yum just walk down the tree and offer to remove half the system, instead.
