I have just pushed e-smith-pop3.2.4.0-8.el6.sme to updates.
I believe this may resolve the issues.
Unfortunately I missed this so my apologies (there are some oddities in where packages get built in buildsys and what goes where)
We are still trying to tidy up and release some stuff that has been lying around far too long, and sometimes there have been multiple updates, so in this instance I saw version -7 and pushed it, but missed the -8 which was in a different repo.
Please bear with us as we are still learning.
