popminpoll and load

[Phil Chambers]

With our former UW server there was a major load issue with POP users who had "leave 
mail on server" set.  With a large inbox each POP connection involved reading and 
parsing the whole inbox, just to find out that there was nothing new.  I patched the 
code to restrict the connection frequency to control the load.

When I set up cyrus I set popminpoll to continue the same policy.

However, I would like to know if I could reasonably reduce the interval or do away 
with it entirely.  Am I right in guessing that with cyrus there is very little 
overhead in pop3d generating the UID list?  I assume it just has to read one of the 
cyrus.xxx files.
