[Dovecot] Disconnects with proxies

I know I shouldn't ask stuff like this when using dovecot-0.99.11-4.EL4
(CentOS-4.4), but why I'm asking this is whether it's worth to switch
from rpm based upstream dovecot to a self compiled one or not and thus I
think you wouldn't kill me presenting you this question. o:-)

I've got a problem with dovecot regarding a pop3 proxy issue.
When I configure my dovecot server to do just plain pop3 I can telnet
from a windows box without any flaw, but as soon as the client uses some
pop3 proxy (for example outlook uses avira antivir Mail-AntiVirus
Protection), queries to that server fail. A log line looks like this:

pop3-login: Dec 05 22:53:24 Info: Disconnected [::ffff:]

Moreover with the proxy activated, a telnet to port 110 (pop3) is not
working properly, the cursor stays right behind "+OK dovecot ready." and
as soon as I enter a character, the server rejects this character as an
unknown command (Without pressing ENTER). As soon as I turn off the
Antivir-Proxy the telnet to
port 110 runs flawlessly and I can login.

So I'd like to know is there anything I can do with this version or is
it worth trying the newest version? Is this a known issue?
Thanks in advance
