It's not simple at all. Because it's a pre-auth command, the proxy server doesn't know what to do with it. The proxy server needs the client to authenticate/log in before it knows whether it already holds an established server connection or has to create a new one. The best it could do is hold a queue of pre-auth commands (offering what amount to fake "OK" responses to each) that would be dumped into the server connection once a auth/login command is received. That's ugly, might be consumptive of memory, and probably wouldn't sit well with clients who expect real responses to each command. You could change the webmail plugin you are using to send the ID command after the user is logged in and everything should work as-is, with only the login command not having the remote IP address associated with it in your logs. You could use a plugin that logs separate data straight from the webmail software that documents the IP address where the user logged in from (in SquirrelMail, this is supported by the squirrel_logger plugin). I might add a limited implementation of the preauth command queue (per above), where it only holds one ID command. I'll reply again if I get around to it. -- Paul Lesniewski SquirrelMail Team Please support Open Source Software by donating to SquirrelMail! http://squirrelmail.org/donate_paul_lesniewski.php ------------------------------------------------------------------------------ ----- squirrelmail-imapproxy mailing list Posting guidelines: http://squirrelmail.org/postingguidelines List address: squirrelmail-imapproxy@lists.sourceforge.net List archives: http://news.gmane.org/gmane.mail.squirrelmail.imapproxy List info (subscribe/unsubscribe/change options): https://lists.sourceforge.net/lists/listinfo/squirrelmail-imapproxy
