[PERDITION-USERS] keeping the outbound connection connected when client disconnects

I am looking for a solution where I need to connect multiple times over time to a 3rd party POP3 SSL server using my webmail interface, but that server only allows me to connect 5 times in 15 minutes. Meaning: I am looking for a solution where the outbound (real server) connection stays established even though the inbound connection (client) temporarily goes away. imapproxy provides such functionality but cannot be used for other reasons. Perdition looks like a good solution, but whenever the client terminates the connection, the associated process terminates as well. On the other hand I see config parameters such as "timeout" that lead me to the assumption it could be possible to set up what I need. Any advise appreciated. Thanks, Rick
