I just use vpopmail and tcpserver here. Was that insufficient for your needs or does the method you describe offer something more/different? I have quite a few concurrent pop3 users (maybe 50-70, not 100 [yet]) and maybe half of that in IMAP sessions but haven't run into any problems with tcprules. Mind you I'm using courier-pop3d and courier-imapd instead of qmail-pop3d. Regards, Andrew
