#   outlook-pop3-no-nuls:
#     Outlook and Outlook Express hang if mails contain NUL characters.
#     This setting replaces them with 0x80 character.


It isn't exactly .99 it is .99 with the famous RedHat backporting of fixes, so
it is somewhere between .99 stable and whatever 1.0 beta that they ported
from. If you look in the stock config file, it is very well commented. I
haven't enabled any workarounds, and haven't had any complaints since the
initial migration and duplicated messages, but you can experiment with
outlook_idle and outlook-pop3-no-nuls. Make sure that the locking is the same
as your MUA and delivery agent. In CentOS 4 it should be fcntl.
In CentOS 3 I think it should be flock, but don't hold me to it.
