Qpopper

Qpopper is a widely used server for the POP3 protocol. It includes TLS/SSL support, very fast start-up times, and reduced I/O at session close. This server is fully compliant with RFCs 1939 and 2449, and supports Kerberos V4, if enabled.

            Mail check speed
            I'm using Qpopper 4.x and I have a problem.
            I thought it was the configuration that made this slow.
            but now i have another configuration.
            P90. 64 MB's of Ram.

            If I do a mail check and the client connects to Qpopper.

            Then it goes fast checking if there is no mail (added)
            But if there is...
            The verifiing takes about 1 minut and the
            close connection about 1 to 1,5.

            I'm using the cash option.
            And now my question is, how can i make this quicker?
            If this possible?

            Maybe you can help me a little bit further.

            Kind Regards,

            Qpopper -> .PID
            I'm still missing the creation of an .pid file, when qpopper is started. Is this feature on your future plans of implementation or am I just overlooking this?

            Standalone mode was new to Qpopper (it is usually run
            from inetd). I believe the problem with zombie
            processes on some platforms is fixed in current
            versions (Qpopper 3.1.2 and Qpopper LX 4.0b11).

            Beware!
            Under Solaris 8, this left about 50 zombies around in standalone mode before I ixnayed on the .13ay. I don't think this is quite a final release IMHO.
