Hello, On a 2.6 Kernel (linux-2.6.18.1) pop connections stop working completely. People are able to connect once (sometimes) and then the pop3 server will not let them connect again. The connection hangs until timeout. When we switch back to a 2.4 Kernel (linux-2.4.33.3) everything works like a charm. IMAP does not seem to be affected. We told our client base to use this until we determined the problem (couldn't believe it was the kernel). We built the 2.6 kernel from scratch and from the generic smp config provided with the distro (thinking we missed something). Both had the same result. In syslog we are seeing the following error on either a 2.4/2.6 kernel, so I don't think this is an issue but it might be.
