Timo,
Please check the code. I didn't add it, but a real_lip might be useful for some people as well. Also, I notice that pop3-proxy is doing a different xsession than the imap proxy. Is there an xsession standard that is different between the two, or just an oversight in the code? Both send the remote address/port, but only imap proxy sends the local address/port.
This patch declares long variable %{real_rip} so that a backend server can declare a different login_log_format_elements login_log_format_elements = user=<%u> method=%m rip=%r lip=%l pip=%{real_rip} mpid=%e %c
This is primarily useful for backend servers to log both the rip, lip, and in case of xsession, the real rip. I haven't done extensive testing yet, but as long as nothing does anything weird elsewhere in the code, it should be good.
