what's with the commas in the cyrus-imapd release tag?

Well, decide yourself:

  $ rpm -qpR cyrus-imapd-devel-2.2.6-2,FC3,3.i386.rpm 
  cyrus-imapd = 2.2.6-2
  FC3  
  3  
  rpmlib(PayloadFilesHavePrefix) <= 4.0-1
  rpmlib(CompressedFileNames) <= 3.0.4-1

Usually, multiple dependencies can be separated with a comma:

  Requires: foo = 1.0, bar = 2.0

Now if the package's EVR contains a comma, this breaks that format
and e.g.

  Requires: cyrus-imapd = 2.2.6-2,FC3,3

is parsed to

  Requires: cyrus-imapd = 2.2.6-2
  Requires: FC3
  Requires: 3

and "voila!" you've got the wreckage ;)

  FC3 is needed by cyrus-imapd-devel-2.2.6-2,FC3,3
  3 is needed by cyrus-imapd-devel-2.2.6-2,FC3,3
