[Dovecot] 2.2.12 RPM Needed

[Asai]

Greetings,

I'm not very experienced in building Source RPMs and we're in need of a 
Dovecot RPM for version 2.2.12 for CentOS 5.  It seems that the  ATRPMs 
repo maintained by Axel Thimm hasn't seen much activity lately and the 
task of updating a source RPM is more than I have time for as a busy 
developer who does systems admin on the side.

Could anybody recommend another repo where there would be the latest 
Dovecot binaries?  Or perhaps tell me of any gotchas and catches which 
might arise if I go ahead and build 2.2.12 from source over the RPM I 
currently have installed (2.2.10)?

Thanks.
