Hello everyone,
we're setting up a new mailserver for our local school and had chosen
cyrus for imap/pop3. The point is that everything works fine (the whole
authentication thing with sasl etc...) except the pop3d: At first pop3d
works, connecting to port 110 it shows the banner and your're able to
authenticate. But after authenticating and quitting and trying a secound
time, the connection can be established indeed, but you don't get the
greeting banner of the pop3d. It seems to be a dead connection. Moreover
you get a zombie-pop3d-process every time you try to connect. And if you
wait a random time, cyrus seems to "heal" itself and everything works
fine again.
Your server is most likely running out of entropy for OpenSSL to produce
an APOP challenge, which appears in the banner. You'll have to find a way
to provide OpenSSL with suitable entropy, or disable APOP by setting
allowapop:off in imapd.conf.

I have just disabled apop and everything works fine.. Thank you! But
honestly I don't really understand why it works now. What is meant by an
entropy? I didn't find a suitable translation in my dictionaries :-)
